Introduction to Edge Blackening

Feb. 28, 2025

Edge Blackening

Lens edge blackening is an auxiliary part of optical component processing. It is generally done after coating and gluing and before lens assembly. The optical element is blackened with black paint, giving the surface of the element a black appearance that both improves the aesthetic appearance and absorbs and blocks unwanted light. 

Lens edge blackening can be done on an optical surface, such as for systems where the aperture of the light has a precision requirement. For instance, a specific-sized area of the surface of a prism or lens can be coated to avoid the entry of light beyond the aperture into the system. More often, edge blackening acts on optical components, especially on the non-optical surface of the lens, to reduce the influence of stray light and improve the imaging quality of the optical system.
