Parabolic Mirrors

Parabolic reflectors are used to collect energy from a distant source (for example sound waves or incoming star light). Since the principles of reflection are reversible, parabolic reflectors can also be used to focus radiation from an isotropic source into a narrow beam. In optics, parabolic mirrors are used to gather light in reflecting telescopes and solar furnaces, and project a beam of light in flashlights, searchlights, stage spotlights, and car headlights. In radio, parabolic antennas are used to radiate a narrow beam of radio waves for point-to-point communications in satellite dishes and microwave relay stations, and to locate aircraft, ships, and vehicles in radar sets. In acoustics, parabolic microphones are used to record faraway sounds such as bird calls, in sports reporting, and to eavesdrop on private conversations in espionage and law enforcement.



Parabolic mirror are typically designed as a segment of a larger parabola, manufactured from a metal substrate such as aluminum and coated in enhanced aluminum, silver or gold as standard. These mirrors focus light similar to a concave mirror with the significant exception being that the off-axis parabolic design redirects the incident light through 90%.



Custom mirrors may be manufactured in a range of substrates and alternative coatings as required by our customer's specifications including UV and IR coatings and materials and alternative reflection angles.

IR Asphere Lenses

Hyperion Optics works with various infrared materials. In recent years, we have seen a growing demand of IR aspheric components due to their ability to reduce the number of elements within the system while maintaining reliable performance; this makes aspherical parts an excellent choice in Low Rate Initial Production (LRIP) projects. Our aspheric manufacturing capability covers from 0.8 micron upwards to 12 micron for IR application, from a combination of materials needed in order to reach the required application needs.



Equipped with Ametek Single-Point Diamond Turning machine, Hyperion Optics is capable of processing the following infrared and UV materials for aspheric components:



Zinc Sulfide (CVD CLEARTRAN available), Zinc Selenide, Germanium, Chalcogenide glasses (available in both Schott and NHG IRG materials), Calcium fluoride, and Silicon.



Please contact our experienced engineers for performance consultation and print assessment.



MOQ starts at two pieces to ensure optical performance approval. Our fast asphere prototyping has become one of our most popular services for Low Ratio Initial Production (LRIP) projects. We can process both spherical and aspherical parts simultaneously for custom objective and/or eyepiece designs, thereby securing reliable timeline management to meet the tight timing requirement. In addition, we offer competitive pricing for aspheric coating within our prototyping packages.



Our rapid aspheric prototyping / LRIP service in SWIR MWIR and LWIR include:



1. Built to print, Hyperion Optics fabricates aspheric lens and provides inspection report by your print.



2. There is a lack of Chalcogenide materials integration in optical designs for IR applications, which is a big missed opportunity. At Hyperion Optics, the combination of Chalcogenide glasses and regular IR materials can provide a cost-effective solution with superior optical performance.



3. Hyperion Optics runs in-depth mapping and optical performance tests on component-level and/or lens system level products; and provides redesign, optimization, manufacturing, and assembly services.



4. For SWIR prototyping projects, we adopt injection molding processing for Schott and Ohara glasses at prototyping quantities, which can avoid purchasing high-cost raw materials from overseas, and hence dramatically reduces material investment at the prototyping phase.

Basic Tips about Aspherical Lenses

The curvature of the lens of this kind of lenses is better. It maintains the good performance of aberration correction to obtain the required performance. The use of aspheric lenses brings outstanding sharpness and higher resolution, while miniaturization of lenses is possible.





Summary:

Aspherical lens is a constant curvature from the center of the lens to the edge, but the curvature of the lens varies continuously from the center to the edge for aspherical lenses. In photographic lenses, many aberrations must be corrected in order to ensure optical performance. If only the aspherical lens is used to correct the lens, the technical requirements of the lens require a combination of lenses. For special advanced lenses, only spherical lenses sometimes fail to correct aberrations to the level of user satisfaction. Calculation formulas in optical design:



Calculation formulas in optical design

Technical principle:

The radius of curvature of an aspherical lens varies with the central axis to improve optical quality, reduce optical elements, and reduce design costs. Aspheric lenses have unique advantages over spherical lenses, so they are widely used in optical instruments, images and optoelectronics industries, such as digital cameras, vehicle lenses, and high-end micro instruments.



Comparative advantage:

A. aberration calibration

The most prominent advantage of aspheric lenses in replacing spherical lenses is that they can correct the spherical aberration induced by the spherical lens in the collimation and focusing system. By adjusting the surface constant and the aspheric coefficient, the aspheric lens can eliminate spherical aberration to the maximum extent. Aspherical lenses (rays converging to the same point, providing optical qualities) essentially eliminate spherical aberrations produced by spherical lenses (which converge to different points, leading to blurred imaging).

Three spherical lenses are used to increase the effective focal length for the elimination of spherical aberration. However, an aspheric lens (high numerical aperture, short focal length) can be implemented, and the system design is simplified and the transmittance of the light is provided.



B. system advantage

The aspheric lens simplifies the involved elements adopted by the optical engineers in order to improve the optical quality. And improves the stability of the system. For example, in the zoom system, typically 10 or more lenses were used (additional: high mechanical tolerance, high additional assembly procedures, improve the anti-reflective coating), but 1 or 2 pieces of aspheric lens can realize optical quality similar or better, so as to reduce the system size, improve the cost rate, reduce the comprehensive cost system.



Molding process:

A. precision glass molding

Precision glass molding is the process of heating glass materials to high temperatures and becoming plastic. They are formed by spherical molds and gradually cooled to room temperature. At present, precision glass molding is not suitable for aspheric lenses with a diameter greater than 10mm. But new tools, optical glasses, and measurement processes are driving the technology. Precision glass molding, although the cost is high in the design stage (high precision mold development), but after the molding, the production of high-quality products will average the cost of development and the price will become acceptable, especially suitable for the needs of mass production occasions.



B. precision polishing molding

Grinding and polishing are generally applied to the production of monolithic aspheric lenses at one time. With the improvement of technology, the accuracy of lapping and polishing is higher and higher. Most notably, accurate polishing is controlled by the computer and automatically adjusted to optimize parameters. If higher quality polishing is required, magneto-rheological finishing will be adopted. Compared with standard polishing, magneto-rheological finishing has higher performance and shorter time. Precision polishing molding requires specialized equipment and it is currently the primary choice for sample making and small batch testing.



C. mixing molding

The spherical surface of an aspherical lens is cast on by using a spherical molding, and a layer of high polymer aspheric surface is cured by ultraviolet light and cover on it. In hybrid forming, the achromatic spherical lens is used as the base, and the surface is cast with a layer of aspheric surface to eliminate chromatic aberration and spherical aberration at the same time. Fig. 7 is a manufacturing process of a mixed forming aspherical lens. The hybrid aspherical lens is suitable for occasions where additional characteristics are required (simultaneous elimination of chromatic aberration and spherical aberration) and mass production.



D. injection molding

In addition to glass aspheric lenses, there are plastic aspheric lenses. Plastic molding is the injection of molten plastic into an aspherical mold. Compared with glass, the thermal stability and compressive resistance of plastics are poor, and special treatment is needed to obtain similar aspherical lenses. However, the most important feature of the plastic aspheric lens is its low cost, light weight, and easy molding. It is widely used in such fields as moderate optical quality, insensitive thermal stability, and little pressure resistance.



Selection basis:

Various types of aspheric lenses have their own relative advantages. Therefore, for different applications, it is important to choose the right product. Major considerations include batch size, quality, and cost.

A. precision glass molding aspheric lens has the characteristics of mass production and high thermal stability, suitable for a large batch, high quality, and high thermal stability.

B .precision polishing molding aspheric lens has the characteristics of short period sample preparation and no die need, it is suitable for sample production and small batch sample occasions

C. mixed molding aspheric lens with the features a simultaneous calibration of spherical aberration and chromatic aberration features, suitable for wide spectrum, large volume, high quality.

D. plastic aspheric lens has the characteristics of low cost and light weight, suitable for large quantity, the low requirement on quality, moderate thermal stability.

When aspheric lenses are required (without standard products or inventory products), development costs, sample costs, batch prices, delivery cycles and other factors should be taken into account.

Why Use Achromatic Lens?

Achromatic lens is a kind of lens which is made up of two kinds of optical components: positive low refractive index and negative high refractive index. Compared with a single lens containing only a single glass, the dual-lens design can provide additional design freedom for users and further optimize the performance of the lens. Therefore, achromatic lens has more advantages than single lens with equal diameter and focal length.



Achromatic lens has various configurations, among which positive achromatic lens, negative achromatic lens, three-in-one acromatic lens and non-spherical achromatic lens are common. It is important to note that achromatic lenses can be bichromic (dual elements) or triad (three elements), and the number of elements is independent of the number of light corrected by the lens. In other words, double or triple achromatic lenses can correct both red and blue light in the visible range.



The achromatic lens is far superior to the simple multi-color "white light" imaging lens. The two components that make up an achromatic lens (literally "uncolored lens") are combined to correct the inherent chromatic aberration of glass. The achromatic lens is very cost-effective in multi-color illumination and imaging because it can eliminate the difficult chromatic aberration.



Since the axial performance of achromatic lens is not degraded by using larger aperture, it is unnecessary to "reduce" the volume of optical system. "Reducing" aperture refers to reducing the aperture of a lens, such as through a pinhole or aperture, to improve the overall performance of the lens. By making full use of the whole aperture, achromatic lens and achromatic lens system can achieve faster speed, higher performance and more powerful functions than the equivalent system using single lens.

The Design Principles of Infrared Optical System

The infrared optical system refers to the system that works in the infrared band of the optical wave, which is the optical system that receives or sends infrared light waves. In general, the infrared optical system is a category of optical system, which is not different from other optical systems in light energy reception, transmission, imaging and other optical concepts. However, due to the infrared optical system working wavelength infrared region and the photoelectric detector as the receiving element, so it has its own characteristics, different from the general optical system.





The wavelength range of infrared optical system tends to be wide, and there are few kinds of infrared transmission materials available at present. Aberration correction, especially chromatic aberration, is very difficult. Therefore, the infrared optical system adopts the non-spherical reflection system or refraction - reflection system in the structure. With the continuous expansion of infrared application scope and the continuous development of infrared thermal imaging technology, the projective objective cannot meet the requirements of large field and large aperture. Therefore, in recent years, high refractive index and low dispersion crystal materials have been widely used for various refractive lens. Infrared optical system is an infrared detector. In order to improve the detection sensitivity, increase the signal-to-noise ratio, the system USES the package live immersion lens, field lens and light cones of secondary condensing system (also known as detector optical system), and a light engine scanning with all kinds of optical scanner. From the principle of design, most infrared optical systems are designed using geometrical optics.



The characteristics of infrared optical system



Because of the unique properties of infrared radiation, compared with the general optical system, especially the visual and photographic system, the infrared optical system have different characteristics.



1) the radiation band of infrared radiation source is located in the invisible zone above 1 um. Ordinary optical glass is not transparent to 2.5 um. In all materials that are possible to penetrate infrared wavelengths, only a few materials have the necessary mechanical properties and can be given a certain size. This greatly restricts the application of lens system in the design of infrared optical system, which makes the reflection type and the reflex optical system occupy a more important position.



2) nearly all infrared systems are optoelectronic systems. Its receiver is not a person's sleep or a photographic plate, but a variety of optoelectronic devices. Therefore, the performance and quality of the corresponding optical system should be based on the sensitivity and signal-to-noise ratio of the optical system, rather than the resolution of the optical system. This is because the resolution tends to be limited by the size of the photoelectric device, thus reducing the requirements for the optical system accordingly.



3) small field and large aperture. In the case of the application unit detector, because the infrared detector has smaller reception area, the optical field of the general infrared optical system is not very large, and the outer aberration of the axis can be considered less.

Because the reflection system has no color difference, in most cases, it is possible for such a reflection system to eliminate the ball and satisfy the sine condition. At the same time, the requirements of such system objects are not too high, and they require high sensitivity. Therefore, most of the optical systems with large relative aperture, namely small F, are adopted. In general, due to the limitation of processing, the number of F is 2-3.



4) the application of various scanners has become more and more, in order to achieve the goal of scanning the space target by tracking the heating of the imaging and thermal imaging technologies. The scanner can be placed before the imaging system, which has a large size and high power consumption, but has minimal impact on the image quality of the optical system. In addition, the optical system with this scanning system requires the rear focal length of the principal and some special requirements for the it.



5) the wavelength of the infrared band is about 5-20 times that of visible light. In this way, the temperature of the thermal imaging system is lower because of the diffraction limit, which means that the thermal imaging system with high resolution must have a large aperture. This makes the system heavy and costly.
