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.

KTP crystal is mostly used as nonlinear crystals for frequency doubling of solid-state Nd:YAG crystal or Nd:YVO4 nonlinear crystal laser, as it has large nonlinear optical coefficients, wide angular bandwidth and small walk-off angle, broad temperature and spectral bandwidth. KTP crystal also has high electro-optic(E-O) coefficient and low dielectric constant, and large figure of merit, these features make it also widely used in electro-optic application.

 

Advantages of KTP Crystal:

 

Large Nonlinear Optical (NLO) Coefficients

Wide Angular Bandwidth and Small Walk-off Angle

Broad Temperature and Spectral Bandwidth

High Electro-Optic (E-O) Coefficient and Low Dielectric Constant

Large Figure of Merit for an Optical Waveguide Modulator

Nonhygroscopic, Good Chemical and Mechanical Properties

 

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.

Achromatic Lenses

 

Definition of achromatic

Achromatic Spherical Lenses, Cemented Lenses, Bonded Lenses, Doublet, Triplet

 

With over a decade of production experience, we have significantly improved our achromatic spherical and cylindrical lenses manufacturing. From the beginning stage during evaluation, we help customers with material selection for cemented elements, thoroughly analyze potential production risks, and assess the cementing precision definition of the prints.

 

We are able to provide flint and crown glasses bonding solution with meniscus elements edged on optical edging device with precision wedge control. Our achromatic lenses include achromatic triplet lenses, achromatic doublet lenses and achromatic cylindrical lenses. Our production team is also specialized in doublet and triplet fabrication with calcium fluoride (CaF2) lenses, which require special adhesive treatment for extended durability.

 

Our bonding operators carefully pair the individual lenses regarding radius (power), center thickness (CT) to ensure adhesive thickness and accurate CT control for high-precision requirement. We utilize UV curing / cold bonding techniques on different glass materials in order to enable operators eliminating center deviation on upgraded centering station. For doublet and triplet diameters exceed one inch, 0.6 arc min to 0.8 arc min is our standard wedge control precision.

 

We can precisely control the center thickness of doublets to within +/-0.04mm, triplet within +/-0.05mm for airspace sensitive design. A design that includes OHARA and SCHOTT glasses typically take longer due to material supplier’s lead time (>6 weeks); our engineering team can speed up the procurement process by helping you select compatible materials from our glass inventory database and dramatically reduce lead time to within one week to have the substrates ready.
