Product Overview
Description
Product Description
Large Size Ge windows
Germanium (Ge) is a relatively hard, high-density, IR transmitting material that blocks UV and VIS wavelengths but allows IR from 2-16µm. Germanium has the highest refractive index of commonly available IR-transmitters and has low optical dispersion, which makes it desirable in aspects of lens designing where its high refractive index allows otherwise impossible specifications to be built. AR/AR coating or AR/DLC coatingis recommended to improve transmission.
The transmission of uncoated Germanium is around 45% @2-14μm under room terperature but transmission degrades slowly at 100⁰C then more rapidly above 200⁰C. Exposure to higher temperatures can lead to reduction of its performance so Germanium is unsuitable for use in high temperature. Additionally, its relatively high density should be considered where weight is an issue.
