Guide ▶For high power lasers use concave substrates (LCBS) suitable for Laser resonator applications.
WEB Reference Catalog Code/W3143
Attention ▶The back side of the substrate has a ground surface; it is not usable for transmission. For transmission we recommend plano concave lenses (SLB-N).
WEB Reference Catalog Code/W3050
▶For cold-mirror or partial reflection application, please contact our Sales Division for a concave mirror on the back side polished.
▶The outer edge of the concave surface is chamfered, the thickness of the edge varies therefore use the back side of the substrate as datum.
