We produce a wide range of the windows made of various crystal and optical glasses materials for spectroscopy and laser applications, typically for FTIR spectroscopy, thermography, pyrometry, CO2 lasers etc.In order to avoid the influence of interference effects from the surface reflections on the transmission sometimes it is preferably to use the wedged windows.
