Dichroic optical filters consist of thin film dielectric coatings on glass and exhibit sharp transitions between transmitted and reflected wavelengths. dichroic lens are similar to traditional interference filters but differentiate themselves by reflecting all unwanted wavelengths. Consequently our dichroic range also offers minimal absorbance characteristics.

 

Our dichroic filters are available in longpass, shortpass, bandpass, bandblocking and colour correction types over a range of wavelengths. Dichroic shortpass and longpass filters can also act as hot and cold mirrors respectively.

 

Dichroic filters can divide natural light from a certain wavelength into two parts, one of which passes through, and the other is reflected or absorbed. Filters that allow longer wavelengths of light to pass through are referred to as long wave pass filters, and filters that allow shorter wavelengths of light to pass through are referred to as short wave pass filters.

 

The desired spectral range can be achieved by using different dichroic mirror.

Colored Glass Filter

 Colored Glass Filter

colored glass light filters is a performance of the color of the optical filter glass, which absorbs undesired through the band of the way, to precisely select the range of light waves to pass.

 

Tinted glass is a lower cost solution than a schott color glass filters, and tinted glass can be easily extended over a wide band. It is widely used in laser protection, industrial measurement and environmental measuring instruments.

Bandpass Filter

 Band pass filter can separate a band of monochromatic light, the ideal transmittance of band-pass filter through the bandwidth is 100%, while the actual band-pass filter pass band is not the ideal square. The actual band-pass filter generally has a center wavelength λ0, a transmittance T0, a half width of the pass band (FWHM, a distance between two positions where the transmittance in the pass band is half the peak transmittance), the cutoff range and other key parameters to describe.

 

Band-pass filter is divided into narrow-band filter and broadband filter.

 

In general, a very narrow bandwidth or high cut-off steepness will make the product more difficult to process; meanwhile the pass band transmittance and cut-off depth is also a contradictory indicator

 

Hyperion Optics’ bandpass filter design are composed of a stack of equally spaced dielectric layers. The number of layers and thicknesses are calculated with excellent cut-off depth (typically up to OD5 or higher), better steepness and a high transmittance (70% narrowband, 90% broadband).

1. Fluorescence microscopy

2. Raman fluorescence detection

3. Blood component testing

4. Food or fruit sugar detection

5. Water quality analysis

Optical Dome

 Glass domes are widely used for commercial applications which require protective boundary between different environments; domes perform as windows, providing protection to electronic sensors or detectors without sacrificing field of view.

 

Composed of two parallel optical surfaces, domes have no optical effect on design optical path. In lead element in an optical system, a dome is exposed to the environment, N-BK7 is good choice for visible to near infrared lead applications, which will withstand wind and rain erosion. Typically in single-use defense applications and ocean exploration. Shapes can vary from hemispheric to custom size with coatings.

 

At Hyperion Optics, we have strict control of wall thickness variation spec by utilizing most reliable deterministic CNC machine tools, we grind and polish optical glass, fused silica and zinc sulfide for applications range from visible to infrared.

 

N-BK7 and H-K9L domes: N-BK7 domes are available directly from stock, and are used primarily in meteorology applications. BK7 offers excellent transmission from 300nm up to 2µm. BK7 is a relatively hard material, with excellent chemical durability. Our custom K9 Dome are practically free from bubbles and inclusions, making them perfect for high performance visible applications.

 

UV fused optical dome: For applications operating in the deeper UV range, we offer a range of UV fused silica domes. Fused silica domes are commonly used in underwater applications at extremely high pressures. Our Corning 7890 2G and Spectrosil 2000 fused silica both offer over 85% transmission at wavelengths as low as 185nm.

 

ZnS Dome: For infrared applications we can provide sapphire domes. Sapphire is an extremely hard material with transmission of over 80% in the 2-5µm wavelength range. As with fused silica, sapphire is able to withstand extreme pressures, making it the perfect material for underwater camera and infrared-guided missile applications.

Fluorescence Filters

 

Fluorescent filter are a class of filters classified by application type.

 

Fluorescence Filter is a fluorescence imaging filter for biomedical and life science instruments, the key components, the main role is in the biomedical fluorescence analysis system for the separation and selection of substances in the excitation and emission fluorescence Of the spectral characteristics of the band. It is usually required that the filter cut-off depth be greater than OD5 (optical density, OD = -lgT). The core requirements for filters used in fluorescence detection systems are high cut-off steepness, high transmittance, high positioning accuracy, high cut-off depth, and excellent environmental stability.

 

fluorescence microscopy filters is a combination of three, three are excitation filters, emission filters and dichroic filters.

 

Excitation Filter (Exciter Filter, Excitation Filter, Excitation Filter): In the fluorescence microscope, only the excitation wavelength of the filter can pass through the fluorescence. In the past, a short-pass filter was used, and now a band-pass filter is basically used. The housing is marked with arrows indicating the direction of propagation of the recommended light.

 

Emission Filter (Emitter Filter, Emitter): Select and transmit the fluorescence emitted by the sample, the other range of light cut-off. The wavelength of the emitted light is longer than the wavelength of the excitation light (closer to red). A band-pass filter or a long-wave-pass filter may be selected as the emission filter. The housing is marked with arrows indicating the direction of propagation of the recommended light.

 

Dichroic Mirror (Dichromic Beamsplitter, Dichromatic Beamsplitter): also known as dichroic mirrors or dichroic mirrors. And placed at an angle of 45 ° to the optical path of the microscope. This filter reflects one color of light (excitation light) and transmits another color of light (emitted light), the reflectivity of the excitation light is greater than 90% and the transmittance of the emitted light is greater than 90%. The impervious portion of the spectrum is reflected rather than absorbed. Filter in the transmitted light and reflected light color complement each other, and thus also known as dichroic filters.

 

Our fluorescence filters are designed for fluorescence imaging applications, with durability in mind and high-performance optical specifications in manufacturing. The filter substrate is made of quartz, which can achieve 1/10 lambda surface accuracy, while the thermal expansion coefficient of quartz is relatively small, can obtain higher image quality.

Asphere Lenses

 

The complex surface profile of an asphere can significantly reduce or even eliminate spherical aberrations comparing to spherical lenses. Hence, asphericals have been increasingly more widely explored and adopted during the optical design stage.

 

Aspheres can replace a complex multi-element spherical system to achieve a lighter and more compact optical system. The resulting design has higher transmittance and in most cases, costs less than the multi-lens spherical design, especially at production volumes.

 

Hyperion Optics is equipped with the Optotech aspheric CNC machine that offers Contour Deterministic Micro Grinding (CDMG) service – the machine grinds the optical material to achieve ultra-high precision shape by leveraging the accuracy and repeatability of a computerized, numerically-controlled machine mechanism. Our process begins by grinding the bulk raw material into the closest fitting sphere, and then contouring the aspheric shape from edge to center. Typical available materials within our fabrication capabilities are optical glass, ZnSe, ZnS, BaF2, GaAs, and aspherical lens glasses types. We also accept materials supplied by our clients

 

Optical Machining Centers capability:

 

Capacities from 5mm to 400mm

 

1,000 to 24,000 rpm tool spindle

 

Automatic curve correction

 

Tool & Workpiece probing system

 

Dual tool spindles option

 

Hyperion’s manufacturing procedure eliminates the need for additional investment on tooling and processing fixtures for spherical substrates and preparation, thereby giving customers a quick start to the production schedule. While the aspheric part is being grounded, the profilometer will conduct and transfer measured data to the polisher. In our polishing process, our experienced operators can control the aspheric form error within 1 micron (depending on the diameter of the parts).

 

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 a 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 package is ideal for you if:

 

1.   Off-the-shelf aspheric parts do not fit perfectly in your system, Hyperion Optics can design and manufacture the custom aspheric lenses based on your system-level optical requirements.

 

2.   You need custom, built-to-print aspheric lenses. Hyperion Optics fabricates custom aspheric lens and provides complete inspection reports per your print requirements.

 

3.   Reverse engineering is required on an existing lens where you need to replace. Hyperion Optics runs in-depth mapping and optical performance testing on all lens products prior to reverse engineering; then, we proceed to redesign and system optimization and finally, manufacturing and assembly.
