Product Description

LBTEK dielectric concave mirrors use N-BK7 substrates, with a broadband dielectric coating applied to the concave surface, suitable for beam collimation, focusing, and imaging. Currently, LBTEK offers dielectric concave mirrors covering three wavelength ranges: 400-750 nm, 750-1100 nm, and 1100-1650 nm. The average reflectance of these mirrors within their operating wavelength range is greater than 99%. Additionally, dielectric concave mirrors are available in seven different focal lengths, ranging from -25 mm to -500 mm, all with a one-inch diameter. Besides standard products, LBTEK also provides customization services for size, focal length, and operating wavelength. 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 concave mirrors are made of N-BK7 substrates with a broadband dielectric coating on the concave surface (frosted backside), suitable for beam collimation, focusing, and imaging. These mirrors offer high reflectivity (Ravg > 99%) within the 400–750 nm wavelength range. Currently, LBTEK provides dielectric concave mirrors in a one-inch size with a center thickness of 6.0 mm, compatible with one-inch mirror mounts. The available focal length options range from -25 mm to -500 mm, covering seven different focal lengths. In addition to standard products, LBTEK also offers customization services for size, focal length, and operating wavelength. For inquiries, please contact LBTEK technical support.
