Calcium Fluoride (CaF₂) Aspheric Lenses
Illustration
Product Overview
Uncoated aspheric lenses made from single-crystal calcium fluoride (CaF₂). Select the diameter, source-listed focal length and center thickness. The design wavelength is 2 µm. Aspheric surface form error is specified in PV micrometers; planar surface flatness is specified separately at 633 nm. Focal length is retained as listed, without assuming effective focal length. Transmission range, numerical aperture and fabrication method require confirmation.
