Optical Coatings

Abrisa provides reliable, precision optical coatings for a myriad of industries and countless applications. Our optical coatings include standard, off-the-shelf coatings as well as many unique and custom coating solutions designed to meet the most rigorous customer specifications. For most of our coatings, we can adjust the wavelength region (shorter or longer) to fit the custom requirement. With lean manufacturing processes in place, we can deliver affordable, precision thin film coatings on a wide variety of substrates, from prototype to high volume quantities.

Our optical coatings are applied via electron beam guns or ion-assisted deposition to influence and control reflection, refraction, absorbance, resistance, glare, and electrical activity. We provide high-efficiency coatings for industrial, commercial, and opto-electronic use in a broad variety of applications.

Abrisa provides precision coatings for lenses, filters, prisms, mirrors, and windows. For more information, please call 805-525-4902.

Anti-Reflective
AR coatings are often crucial components in optical systems with multiple lenses or other optics where the maximum possible light energy is needed. AR coatings help to produce brighter images. AR coatings also reduce the intensity of ghost images which are sometimes produced in optical systems by multiple reflecting surfaces.
ZC&R commonly deposits various standard and custom AR coatings. AR coatings are generally separated into two groups. The first group is made of AR coatings that target one or more broad wavelength bands. Our BARC coatings are examples of this group.

Bandpass Color Filters

Beamsplitters
Beam-Splitter (BS) is a term used to describe various coatings which divide a beam of light into separate beams. Dichroic filters, covered in our Color Filter section, are often called beam-splitters. However, in this section, we will be speaking specifically about beam-splitters that divide light at each wavelength of interest into the two separate beams with an incident angle around 45 degrees from normal.
Dielectric coatings, however, have the advantage of being non-absorbing and so allow for greater throughput of energy. For example, a dielectric coating can be used for a 50/50 beam-splitter coating. Inconel, on the other hand, can yield approximately 30% transmission and 30% reflection due to the absorption inherent in the metal film. Standard dielectric beam-splitter coatings include 30/70, 50/50, and 70/30. However, we would welcome any custom requirements you may have. Please feel free to contact us with your specifications.
Partially transmitting metals make very useful beam-splitter coatings. Two common metals used for this purpose are Inconel and chrome. Metal beamsplitters are often very broad and can cover a much wider spectrum of wavelengths than their dielectric counterparts.

Cold Mirrors

Color / Temperature Correction
Dichroic color filter coatings are an excellant alternative to dyed plastics and glass. Unlike plastic color gels which age and breakdown relatively quickly during use, dichroic filters are designed to stand up to the heat and UV energy in high energy light sources.

Contrast-Enhancing Filters

Covert / Semi-Covert Filters

Cut-Off Coatings
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.

Heat Control
Heat control filters are a special type of dichroic filter used to remove unwanted energy from the light emitted by a source. A common example is the use of hot mirrors in very bright spotlights used in entertainment applications. Heat control filters are able to separate the unwanted infrared, perceived as heat by people, from the visible light desired.
