GALLIUM ARSENIDE(GaAs) PLANO-CONCAVE LENSES Download PDF document

Gallium arsenide plano-concave lenses have a very low absorption in the infra-red. Nogtive focusing GaAs lenses are perfect for thermal imaging and Carbon Dioxide laser focusing applications.

We supply uncoated but a range of anti-reflection coatings can be applied as well.
