67-492 10.0mm Dia. x 100.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-492 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 10.0mm and a focal length of 100.0mm, making it suitable for a wide range of applications. The lens is made from n-BK7 Schott, a popular optical glass known for its excellent transparency in the visible and near-infrared regions.
The lens features a standard curve coating on both the front and back surfaces, specifically the EDM NIR-II coating. This coating is designed to enhance the lens' performance in the near-infrared region, specifically between 750nm and 1550nm. The coating helps to reduce reflection and increase transmission, making it ideal for use in applications such as biomedical imaging, spectroscopy, and optical communication.
The geometry of the lens includes a thickness of 2.51mm at the edge and 3.0mm at the center. The lens' effective focal length (EFL) is 50.0mm, and the radius of curvature (R1) is 25.84mm. The back focal length (BFL) is 48.02mm, and both the inner and outer radii are 0mm.
