Product Details
BK7 Window High Thermal Expansion Coefficient For Optical System
Windows are widely used on optical system. There can be extreme
differences of temperature, pressure, humidity and other parameters
on either side of the window. The optical, mechanical and thermal
properties of windows including BK7 windows. Fused silica
windows,CaF2 windows, Sapphire windows.
Mirror are designed for visible light; however, mirrors designed
for other types of waves or other wavelength or electromagnetic
radiation are also used. Especially in non-optical instruments.
Product description:
The window is made from BK7 material, which has transparent range
from 330-2100nm. The refractive index is 1.5164 at 588nm. The
BK7window has good performance over visible and near IR spectrum
for most application.
