5x0.5 mm Germanium Round Optical Window, AR Coated

Product description

Germanium optical windows are designed for thermal imaging applications, offering excellent transmittance in the 8-14 μm and 400-700 nm bands. With a range of diameters from 5.0 mm to 500.0 mm and thicknesses from 0.5 mm to 20.0 mm, these windows are ideal for infrared applications requiring low dispersion and high opacity in the visible spectrum. The material’s low peak absorption makes it suitable for CO2 laser cavities, ensuring reliability in demanding environments.
