plano-concave reflector lens

We manufacture customized plano-concave (diverging) spherical lenses and plano-concave spherical mirrors from N-BK7, fused silica, or IR materials (Si, Ge, ZnSe) per customer drawing.

Lenses are supplied with AR/BBAR or V-coating on curved and/or plano surfaces; mirrors receive protected gold, silver, aluminum, or dielectric HR coating on the concave surface with the plano side typically blackened or AR-coated.

Ideal for beam expansion/divergence control, telescopic optics, laser cavity mirrors, and IR imaging systems. Full in-house metrology ensures λ/10 surface irregularity and precise radius control. OEM/ODM drawings accepted (DWG / STEP / Zemax prescription).
