Rectangular Windows
- have high transmittance, low wavefront distortion and low scatter
- are durable and strong
- BK7 glass is economical and ideal choice for high quality visible applications
- FS is most physically robust and has lowest coefficient of thermal expansion
- UV FS has deepest UV range and highest transmittance
Windows are used to allow optical radiation to pass from one environment to another without allowing other components of these environments to mix. Considerations in selecting windows may include transmission, scattering, wavefront distortion and resistance to certain environments. The ideal window allows an optical beam to pass from one medium to the next without changing the wavelength distribution of the beam, the transmitted wavefront or scatter any of the light out of the beam. We offer windows of three different materials, from which you may choose in accordance with the properties you need: BK7, fused silica and UV grade fused silica.
Windows can be anti-reflection coated. For required coating please refer to the COATINGS section.
Diameter up to 250 mm is available on request.
