Product Description

Uncoated or with AR Coatings Designed for 3-12μm or 8-12μm
Minimal Chromatic Aberration Due to Low Dispersion
Ideal for Infrared Applications Requiring Rugged Optics
Germanium (Ge) leness are available off-the-shelf with two anti-reflection coating options: 3 - 12μm for mid-infrared or broadband multi-spectral applications, or 8 - 12μm for thermal imaging applications. Due to its high index of refraction (around 4.0 from 2 - 14μm), an anti-reflection coating is recommended on these germanium windows for sufficient transmission in the region of interest.

Materials	Germanium
Dimensional Tolerance	± 0.1mm
