Noticed:
--Germanium windows, opaque in the UV and visible parts of the spectrum, have a broad transmission range and are well-suited for IR applications. Germanium is a very hard, high-density material - characteristics that are advantageous where robustness is needed. Germanium's high density also makes it heavy, something to be considered when designing it into optical systems where weight is a consideration. Another characteristic of Germanium is thermal runaway, which means that its transmissive properties decrease as temperature increases.
- We offer other dimension Ge windows and lens,please contact us if you need others which are not in our store now
