Dia25.4mm EFL-75mm CaF2 Plano Concave Lens Uncoated, Code: 1110-004

Plano-concave lens is a type of concave lens component with an asymmetric lens structure (one flat surface and one inward-curved surface) contributing to a negative focal length. Plano-concave lens could be used for light collimation, diverging, and the enlargement of the focal length of a lens group. CaF2 is an excellent optical material of high transmission in the UV to IR spectral ranges. Its high laser damage threshold and outstanding durabilities to thermal/mechanical/chemical attacks enable its incorporation into UV optical systems, IR lens groups, and high-energy lasers such as excimer lasers.

Shalom EO is a professional supplier and manufacturer of CaF2 plano concave lenses, both stocked and custom versions are available.
