5x0.5 mm CaF2 Optical Window, AR Coated

Product description

Calcium fluoride (CaF2) windows are ideal for thermal imaging and spectroscopy applications, offering high transmittance from 0.18 to 8.0 microns. With a surface quality of 60/40 and a clear aperture greater than 90%, these windows ensure optimal performance in UV and IR environments. Their robust design, including low absorption and high damage threshold, makes them suitable for demanding applications, including excimer lasers and cryogenic systems.

Key Features

Transmittance >92% across 0.18-8 μm enhances imaging quality.
Custom sizes available, including variants like 177.5 mm diameter and 25.2 mm thickness.
Surface quality of 60/40 ensures reliable optical performance.
Parallelism < 3 arcmin for precise alignment in optical setups.
Broadband AR coating option increases transmission in specified ranges.
