Medium Film Concave Mirror, N-BK7, Operating Wavelength: 400-750 nm CM20-F100-A

Medium Film Concave Mirror, N-BK7, Operating Wavelength: 400-750 nm — Model CM20-F100-A

Operating wavelength 400-750 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.

Medium Film Concave Mirror, N-BK7, Operating Wavelength: 400-750 nm

• Working Wavelength: 400-750 nm
• Reflectivity: Ravg > 99%
• Focal Length: -25 mm ~ -500 mm
• Matte Back Surface

LBTEK dielectric coating concave mirrors use N-BK7 or equivalent material as the substrate, with the concave surface coated with broadband dielectric coating (backside ground), and can be used for beam collimation, convergence, and image. The mirror has high reflectance (Ravg>99%) in the 400-750 nm wavelength range. Currently, LBTEK offers dielectric coating concave mirrors in one-inch and two-inch sizes, which can be installed in one-inch or two-inch mirror mounts. The optional focal length (f) range of dielectric coating concave mirrors includes seven focal lengths from -25 mm to -500 mm. In addition to standard products, LBTEK also provides custom solution for size, focal length (f), and wavelength range. If needed, please contact LBTEK technical support.
