Concave Mirror Substrate 20mm Diameter 400mm Focal Length
LCBS-20C05-800
These concave substrates are the primary substrate used by mirrors for the laser resonator. It is processed with high surface flatness on both the front and back surface of the concave mirror. Concave mirrors are also available with a dielectric multi-layer film with high laser damage threshold.
◦Large selection of diameter and focal length is available on our website and in our catalog.
◦Because it is also polished on the back side, it is possible to use for input of excitation laser or extraction of sample beam.
◦The substrate can also be used as a test plate for convex lens surface because of the high accuracy and precision of the radius of curvature.
