In the past, chalcogenide infrared (IR) glasses, also known as chalcogenides, were considered exotic materials owing to their limited demand. However, emerging use cases and a rising interest in ...

Chalcogenide glasses, based on various combinations of the chalcogen elements sulfur, tellurium and selenium, are attractive optical materials thanks to their wide IR transmission window and ...

A groundbreaking sulfur-rich polymer lens for thermal imaging optics shows high refractive index and LWIR transparency, paving the way for sustainable optics.

BaF2 Windows,UV and IR windows In the most general sense, an optical window is flat piece of material, transparent at some portion of the electromagnetic spectrum from UV to IR, that allows the ...
