45-492 15.0mm Dia. x 22.5mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-492 is a Plano-Convex lens, a type of spherical lens, with a diameter of 15.0mm and a focal length of 22.5mm. This lens is sourced from Edmund Optics, a reputable vendor in the optical industry. The lens is made from n-sf5 Schott, a high-quality optical material known for its excellent transmittance and durability.
The lens features a front and back coating of edm visnir0sp2002000, a VIS-NIR coating that enhances its performance in the visible to near-infrared spectrum, specifically between 400-1000nm. This coating is designed to reduce surface reflections and increase transmission, making it ideal for applications that require high light transmission and clarity.
The lens has a thickness of 1.36mm at the edge and 3.35mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a flat surface on the non-curved side of the lens. The effective focal length (EFL) is 22.5mm, and the radius of curvature (R1) is 15.12mm. The back focal length (BFL) is 20.5mm.
This lens is versatile and suitable for a wide range of applications, including but not limited to imaging, beam shaping, and light collimation. Its high-quality material, advanced coating, and precise geometry make it a reliable and efficient optical component for various projects and systems.
