Calcium Fluoride (CaF2) Windows have a high damage threshold and low absorption and are transparent from 180 nm to 8µm. It is a great choice for FTIR analysis, excimer laser systems, spectroscopic windows, and thermal imaging systems.

Features:

  • <1 arc-minute parallelism
  • Ideally suited for excimer laser applications.
  • Transparent in UV, visible, and infrared light.
  • A low absorption rate and a high damage threshold
  • In comparison to other IR materials, it has a low chromatic aberration.
