LaserLens, Plano-Concave, -152.4mm FL, ∅12.7mm

Ealing’s line of LaserLenses™ are ideal for most laser applications. They are made of UV grade fused silica which can withstand the thermal heating from a laser beam much better than glass. LaserLenses have excellent transmission down into the UV spectrum and have been precision polished to minimize scatter and wavefront distortion.
