Optical Windows

Description

Optical window refers to a piece of transparent optical material that allows light into an optical instrument. They are pieces of optical glasses with ground and polished faces that are relatively parallel. Optical windows are applied for protecting fragile optical components inside an equipment, they are adopted to isolate two physical environments while allowing light to pass. A window is usually parallel and is likely to be anti-reflection coated, and may be built into a piece of equipment, such as a vacuum chamber, to allow optical instruments to view inside that equipment.

A wide range of materials could be applied due to varies demands: BK7, Fused silica, Sapphire, Quartz, Silicon, MgF2, CaF2, ZnSe, etc.

Material	Properties	Applications
BK7	Transmission Range: 330-2100nm Refractive Index: 1.5164@588nm	Most popular and low cost Visible and near IR spectrum applications
Fused Silica	Transmission Range: 185-2500nm Refractive Index: 1.4858@308nm Low Thermal Expansion Coefficient: 0.54 x 10^-6K	UV to IR spectrum Best choice for thermal resistance application.
Sapphire	Transmission Range: 180-4500nm Refractive Index: 1.755@1000nm Strong Hardness	Best choice for scratch resistance applications Thinner optics Wide Transmission Range
Calcium Fluoride	Transmission Range: 170-7800nm Refractive Index: 1.399@5000nm Little Hygroscopic Susceptibility High Thermal Expansion Coefficient: 18.85 x 10^-6K	IR laser applications
MgF2	Transmission Range: 120-7000nm Refractive Index: 1.376@700nm	UV laser applications
