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.
Concave reflector mirror substrate (TCBS) is also available for use with a light source or lamp reflector telescope.

Attention
The outer periphery of the concave edge is chamfered and thickness of edge (te) may vary. For this reason, please use the back side as the reference plane.
