Optical Coatings and Materials


Introduction To Optical Prisms
Prisms are solid glass optics that are ground and polished into geometrical and optically significant shapes. The angle, position, and number of surfaces help define the type and function. One of the most recognizable uses of prisms, as demonstrated by Sir Isaac Newton, consists of dispersing a beam of white light into its component colors.  Continue Reading..

Used across a variety of biological disciplines, fluorescence-based flow cytometers rapidly and accurately quantify cells and cellular components. As one of the most important components of these systems, flow cytometry filters must be specifically designed to maximize signal-to-noise ratios while minimizing crosstalk between fluorophores.  Continue Reading..


BOROFLOAT® 33 is a UV-NIR transparent borosilicate float glass with excellent optical properties and smooth low scatter surfaces straight off the float process. It is an economical high performance material, making it ideal for the volume manufacture of windows, mirrors, filters, display glass, 3D build platforms, and other components.

ZC&R Coatings for Optics (ZC&R), an Abrisa Technologies company, designs and manufactures innovative precision thin film coating solutions for micro-electronics, defense and avionics, display, industrial automation, optical sensors and imaging, photonics, medical/dental, life science analytics, and other market applications. 

Abrisa Technologies offers the PRO-HC-VIS1, a protective anti-abrasion hard coat clear glass coating option for high traffic contact scanner applications, which delivers up to 40X more linear taber abrasion resistance when compared to uncoated glass and HIE chemically-strengthened glass surfaces.

Abrisa Technologies provides Dead Front Panels for Backlit Display and User Interface applications that afford equipment designers greater flexibility in achieving the overall clean lines and sleek uncluttered aesthetics they seek.

SCHOTT D263® T eco is a clear, lightweight, low fluorescence, borosilicate glass available from Abrisa Technologies in thicknesses from 0.07 mm to 1.1 mm with excellent luminous transmission and high chemical resistance. 

ITO and Index-Matched (IMITO) transparent, high transmittance conductive coatings are extremely useful in EMI Shielded windows for sensors and displays, heated outdoor camera windows, liquid crystal based polarization devices, and photovoltaic cells.

LASER COMPONENTS has developed a new optics layer design that has the ability to separate the polarizations of three wavelengths simultaneously. These new trichroid thin-film polarizers can be used to combine linearly polarized laser beams from several sources, even if they have the same or different wavelengths.

At Alluxa, we are continually striving to improve our products by researching and developing novel thin-film technologies. Therefore, we welcome any custom optical filter requests for non-standard spectral shapes, unusual coating materials, tunable filters, extreme blocking, or any other challenging technical specifications.
