Medium Film Concave Mirror, N-BK7, Operating Wavelength: 750-1100 nm — Model CM20-F100-B

Operating wavelength 750-1100 nm, focal length -100 mm, Ø50.8 mm, substrate N-BK7.

Product Description

LBTEK dielectric-coated concave mirrors are made of N-BK7 or equivalent material, with a broadband dielectric coating on the concave surface, and can be used for beam collimation, focusing, and imaging. Currently, LBTEK offers dielectric-coated concave mirrors in three wavelength ranges: 400-750 nm, 750-1100 nm, and 1100-1650 nm. The average reflectance of these mirrors is greater than 99% within the specified wavelength range. Additionally, the dielectric-coated concave mirrors are available in seven different focal lengths ranging from -25 mm to -500 mm, with sizes of one inch and two inches. In addition to standard products, LBTEK also provides custom solutions for size, focal length, and wavelength range. If needed, please contact LBTEK technical support.
