For an entire breakdown of ways to struggle through the entire major optical window choices check our optical window guide.
Nearly anything around a hundredºC is not recommended. By the point it reaches two hundredºC it is almost opaque in the least wavelengths. If you want a substantial temperature window, you’re superior suited to follow a fabric like MgF2, YAG or our outdated Good friend sapphire.
Element of The key reason why for That is larger powered lasers induce temperature raises, drastically dropping transmission Qualities over 100ºC and eventually damaging the substrate by itself after temperatures around 600ºC are arrived at.
