Hi,
Would anyone know if I can get Chalcogenide glass without Arsenic in it please? I'm looking into machining it for infrared lenses but don't really want arsenic ust flying about the place.
Also, is there a site I can look up Toxicity information that's free please? I have looked- spent hours doing so but can't find any that are free. I'm specificay looking for the other constituents of chalcogenide which I beleive are selenium and other weird stuff.
Many thanks in advance. :drowning:
