5 mm CaF2 Concave Lens, AR Coated

Product description

The CaF2 concave lens is designed for applications in thermal imaging, LIDAR, and general imaging across the UV to visible spectrum (400-700 nm). With high transmission and low dispersion characteristics, it provides superior imaging performance compared to conventional optical glasses. This lens is ideal for environments requiring high laser power damage thresholds, making it suitable for excimer laser applications. Custom sizes and coatings are available to meet specific project needs.

Key Features

High transmission from 180 nm to 8.0 microns for versatile applications.
Clear aperture greater than 90% ensures minimal light loss.
Surface quality of 60/40 for reliable optical performance.
Centration tolerance of less than 3 arcmin for precise alignment.
Custom OEM/ODM options available for tailored solutions.

Applications

Thermal Imaging, Lidar, Imaging
