The KPA016-C Aspheric Condenser Lens is a 400 to 700 nm anti-reflection coated Aspheric Condenser Lens, with a 12.0 mm diameter and a 8.0 mm effective focal length. It is fabricated using B270 glass providing excellent transmission in the visible to near-infrared regions. The aspherical surface is precision molded, while the convex back surface is ground and polished. Ideal for light collection, projection, illumination, detection, and condensing applications.
