Precision glass windows
Description
These optically-polished plates are useful not only as windows but as substrates for special beamsplitters etc. The good standard of flatness (λ/4 both sides) renders these windows suitable for most high-quality imaging applications. In addition to uncoated windows, we offer a choice of AR coatings with ranges covering the visible/NIR (450-900nm), the NIR (630-1100nm) and the telecoms wavelengths (1100-1600nm). See curves in technical tab below..
