Broadband Dielectric 90° Specialty Mirrors

Broadband Dielectric 90° Specialty Mirrors

Broadband Dielectric 90° Specialty Mirrors

×

TECHSPEC® Broadband Dielectric 90° Specialty Mirrors are constructed from right angle prisms with a dielectric mirror coating on the two legs and an uncoated hypotenuse. The mirrored surfaces form a precise 90° angle, ideal for splitting an image from a single imaging lens onto two different cameras, or for combining two images onto a single camera. These mirrors are available in a range of sizes from 5 – 75mm and coated on an N-BK7 substrate. TECHSPEC® Broadband Dielectric 90° Specialty Mirrors feature greater than 99% reflectivity from 400 – 750nm, increasing system performance by decreasing energy loss compared to standard metal coated mirrors.
