Previously mentioned price are generic technical specs for fabrication, specific far better worth could possibly be offered and should be reviewed situation by circumstance.
Anything more than 100ºC isn't advised. By the time it reaches 200ºC it is nearly opaque at all wavelengths. If you want a superior temperature window, you’re better suited to stick with a cloth like MgF2, YAG or our aged Close friend sapphire.
Element of The key reason why for That is better run lasers cause temperature improves, dramatically dropping transmission Houses above 100ºC and ultimately harming the substrate by itself once temperatures in close proximity to 600ºC are reached.
Germanium retains the high ground In regards to transmission range acquiring that more protection from 7-16µm, which silicon lacks. Along with this, germanium has better electrical conductivity rendering it a far more suitable candidate as an optical element in laser devices.
