For harsh environments Polarizers and germanium windows

The new Corning Polarcor glass polarizers distributed by Edmund Optics and Techspec diamond-like carbon (DLC) coated germanium windows manufactured by Edmund Optics are ideal for applications in harsh environments.

The polarizers feature high extinction ratios and low insertion loss for the NIR spectrum. Additionally, they are resistant to chemical, physical, and thermal damage, making these polarizers suitable for high power applications. The polarizers are available in a range of standard sizes that can be customized.


The DCL-coated germanium windows feature transmission of 90 % or higher at wavelengths ranging from 8 to 11,5 µm and meet the severe abrasion requirements of MIL-C-675C. They are also designed to withstand temperature cycling from -80 to +120 °C, salt solubility for a 24-hour immersion period, salt spray for a continuous 24-hour period, and 5.000 wiper oscillations in a sand and slurry mixture.
