Optical Windows

Optical protective windows with custom coatings to maximise transmission in a specific wavelength range while minimising reflection and absorption.

Supplier: Wavelength Opto-Electronic

Technology type: Laser Optics

Wavelength Opto-Electronic (OE) offers high-quality, large-area optical windows with custom coatings to best protect your optical equipment without compromising its performance.

Optical windows made of fused silica and BK7, known for their low coefficient of thermal expansion, high transmission for light from the ultraviolet to the near-infrared range, and low scattering. Coated quartz windows are commonly used in fibre laser cutting and welding systems.

In addition, a range of ZnSe and germanium windows are also available for CO2 laser applications and thermal imaging cameras.

Large dimensions
AR coatings for multiple wavelengths simultaneously
Wide spectral range available

Special coatings for harsh conditions, e.g. maritime, dusty, and sandy environments
Customised coatings and dimensions available on request
