Filters Wavelength & Color
Solutions promoting color or signal separation, signal and “color” isolation, color temperature correction, aesthetic lighting effects, selective wavelength or color illumination, Dichroic color separation, filters for Heads Up Display (HUD).
Bandpass & Notch Filters
Trim filters, also commonly known as cut-off or dichroic filters, are advantageous for a variety of applications. Common uses include optical noise reduction for bar-code readers and wavelength band isolation for fluorescence applications. Trim filters are often used in conjunction with absorptive filter glasses to form band pass filters.
Color Correction & Color Temperature Filters
Dichroic color filter coatings are an excellent alternative to dyed plastics and glass when a beam of light must be split into two distinct beams varying by wavelength. Color correction filters alter the overall color of light to achieve a specific color and sometimes to obtain a specific color temperature. Unlike plastic color gels which age and breakdown quickly during use, dichroic filters and color correction filters are designed to stand up to the heat and UV energy in high energy light sources. High energy light sources can also have a damaging effect on dyed glasses as well, due to their heat absorbing nature. Dichroic and color correction filters have the advantage of reflecting unwanted light instead of absorbing the energy, which allows dichroic filters to be used with much higher intensity light sources up to 550°F. Dichroic color filters are used in a variety of applications including architectural, entertainment, scientific instruments, and engineering. Many industry standard colors have been engineered as dichroic filters. We have over 160 different colors available. Dichroics are offered from 1.1mm (.043”) thick up to 3.3mm (1.28”) thick.
NVIS Filters
ZC&R Coatings for Optics (ZC&R), a division of Abrisa Technologies, has over 20 years of design and volume manufacturing experience for high performance thin film coating solutions for Night Vision Imaging Systems (NVIS) and Night Vision Goggle (NVG) compatible lighting and displays.
Blackeye, Covert & Semi-Covert Filters
Typically used with infra-red cameras, scopes, and night vision goggles for surveillance, these filters enable infrared energy to be emitted from a variety of light sources while blocking visible energy, avoiding detection by the unaided eye.

Longwave Pass (LWP) Edge Filters
Long pass filters block a select band of shorter wavelengths. This example, long wave pass cutoff filter provides average reflectance more than 99% from 400-700nm, 50% cutoff point at 750nm ±10nm and 95% transmission from 780-1200nm. Custom long wave pass filters are available on request.

Common uses include optical noise reduction for bar-code readers and wavelength band isolation for fluorescence applications. Trim filters are often used in conjunction with absorptive filter glasses to form band pass filters.
UV Blocking Filters
Managing ultraviolet (UV) light exposure is critical in a wide variety of applications including some necessary to life. ZC&R has several standard coatings designed to manage UV light for a wide variety of applications. Overexposure to UV can cause skin and eye damage requiring windows and other glass surfaces to be used for protection. Similarly, UV exposure can also damage artwork, documents, and other ink-based items we might expect to find behind UV blocking glass generally found in museums. On the other hand, there is our need for UV exposure in moderation for processes such as vitamin D synthesis. UV exposure is also used in curing applications, fluorescence microscopy for cellular imaging, and even Blacklite lamps for entertainment venues.
