The 38-509-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.5mm, is designed for use within the visible to near-infrared spectrum, specifically between 400-1000nm. The lens has a front (plane) side and a back (curved) side, both of which are coated with the EDM VIS-NIR 0SP2002000 coating, enhancing its performance within the specified wavelength range.
The lens has a thickness of 1.23mm at the edge and 2mm at the center, with a focal length (EFL) of 50mm. The radius of curvature (R1) is 25.84mm, and the back focal length (BFL) is 48.68mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
This lens is a valuable addition to any optical system that operates within the visible to near-infrared spectrum. Its compact size, coupled with its high-quality coating and material, ensures reliable and efficient performance.
