Near Infrared (NIR) Coatings
Abrisa supplies an array of near infrared coatings (NIR) that include BBAR BARC-11, BBAR Optimized for Telecommunications, and Narrow Band AR.
BBAR BARC-11
This broadband coating provides a low level of reflectance across a wide spectrum from 400-1100nm, reflecting less than 1.0% average. Standard and custom coatings are available for refractive indices of 1.46 to 1.90.
BBAR Optimized for Telecommunications
This broadband AR coating is particularly designed for telecommunication applications. It provides a low level of reflectance to less than 0.25% average from 1450-1650nm. Standard & custom coatings are available for refractive indices of 1.46-1.90
Narrow Band AR
NOMINALLY CENTERED @1550 NM
This narrow band AR is an excellent coating for targeting a single wavelength or very narrow band of wavelengths at or near 1550nm. Standard < 0.25% and high performance < 0.05% reflectivity specifications are available.
