Product Description

 is the most common type of window. It has good performance over visible and near infrared wavelength region. At the same time,BK7 window is ideal for applications require minimal transmitted beam deviation. It is suitable for coating AR film.

Specificaitons:

Material	Properties	Applications
BK7	Transmission Range:330-2100 nm Refractive Index:1.564@588nm	Most Popular and low cost Visible and near IR spectrum applications
Fused Silica	Transmission Range:185-2500nm Refractive Index:1.4858@1308nm 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 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

It is also available to supply the coating wavelength curve, such as AR coating,BBR coating,filter coating and so on.
