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

Product description

Germanium windows are essential for thermal imaging applications, offering high transmission in the infrared spectrum (1.7-14 μm). With a high index of refraction, these round windows enhance imaging performance while providing robust durability. Available in various sizes, including custom diameters from 5.0 mm to 300.0 mm and thicknesses from 0.5 mm to 20.0 mm, they can be tailored to specific project needs. The coatings, including anti-reflection and diamond-like carbon (DLC), optimize performance across multiple bands.
