Edge Blackened Achromatic Lenses for Low-Stray-Light Optical Systems

Edge Blackened Achromatic Lenses are designed for optical systems that require both color correction and stray light control. The achromatic structure helps reduce chromatic aberration by combining optical glass materials with different dispersion properties, while the blackened lens edge helps absorb unwanted light reflection from the side surface.

Compared with standard achromatic lenses, edge blackened achromatic lenses can improve image contrast, reduce glare, and enhance optical system stability. They are especially suitable for imaging systems, microscopes, machine vision, laser optics, medical devices, and high-precision optical instruments.

Realpoo Optics provides custom edge blackened achromatic lenses according to customer drawings, samples, optical design files, or application requirements. We can customize the lens diameter, focal length, glass material, coating, edge blackening method, and mechanical dimensions.
