SIGMAKOKI Laser concave mirror substrate, outer diameter Φ20mm, LCBS-20C series

This is a concave substrate used as a mirror substrate for laser resonators. The concave surface and the flat surface on the back surface are machined with high surface accuracy. You can select from a wide variety of variations subdivided by outer diameter size and focal length according to your specifications. The back surface is also polished, so it is possible to input the excitation laser and extract sample light for power detection. Since the accuracy of the curvature radius and surface accuracy are high, it can also be used as a Newton prototype for convex lenses. We also offer concave mirror substrates (TCA) for reflectors of reflecting telescopes and lamp light sources. *The outer rim of the concave surface is chamfered, and the edge thickness (te) may vary. For this reason, please use the back surface as the reference surface.
