Description
Custom Multispectral ZnSe Optical Dome | Integrated Lens Infrared Dome
Custom multispectral ZnSe optical domes are also known as infrared domes or optical fairings. Made of high-purity zinc selenide, they feature excellent transmittance across visible, near-infrared and far-infrared bands. This hemispherical component acts as a protective enclosure, while the integrated lens structure realizes light focusing and beam collimation, dual functions in one part. We fully customize diameter, wall thickness, spherical radius and surface coating. Widely applied to aerospace airborne devices, defense EO/IR systems, multispectral cameras and outdoor infrared monitoring equipment.
