SO-L11 SERIES

UV Fused Silica Bi-Concave Lens

SO-L11 UV fused silica bi-concave lenses provide symmetric negative power for beam expansion and relay-system focal-length control. Their fused-silica substrate supports ultraviolet and visible optical paths while offering low fluorescence and good resistance to thermal variation.

Product Overview

Configure UV Fused Silica Bi-Concave Lens around focal geometry and coating

Both surfaces are concave, making the series useful where the incident and emerging conjugates are more balanced than in a plano-concave application. Use the negative focal length, equal-surface radius, back focal length and edge thickness to model the assembly accurately.

For highly asymmetric or collimated-beam layouts, compare the aberration performance with a plano-concave lens before selection.
