The Custom Optical Glass Lens Quartz K9 Optical Biconcave Double Concave Focus Lens is a precision-engineered optical component designed for advanced laser, LED, and imaging applications. Manufactured from high-quality quartz or K9 optical glass, this biconcave lens features two concave surfaces that diverge light efficiently, providing precise beam shaping, collimation, or expansion. The negative focal length design allows optical engineers to control light propagation and minimize spherical aberration in complex optical systems.
The Custom Optical Glass Lens Quartz K9 Optical Biconcave Double Concave Focus Lens is suitable for applications requiring high optical clarity, low absorption, and stable performance across visible and near-infrared wavelengths. Optional anti-reflective coatings can be applied to enhance transmission, reduce reflection losses, and improve system efficiency. With customizable diameters, focal lengths, and surface quality standards, this lens is ideal for laboratory research, industrial laser systems, and optical instrumentation.
