Product Description

General Introduction:
Raytek plano-concave lens diverts light and has a negative focal length, with one side flat and the other concave. Often used for beam extension, projection and extension of focal length in optical systems. United Optics provides flat concave lenses with uncoated and anti-reflective coatings.

Lens Substrates:
UV FUSED SILICA

Optional I:	UV FUSED SILICA from CORNING, OHARA, SCHOTT, LEONI, AGC,HELLMA, NIKON,VITRON,ETC
Optional II:	Equivalent UV FUSED SILICA Made in China, C-laser own brands
