67-515 15.0mm Dia. x 15.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-515 is a Plano-Convex lens, a type of spherical lens, with a diameter of 15.0mm and a focal length of 15.0mm. This lens is sourced from Edmund Optics, a renowned vendor in the optical industry. The lens is designed for use in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm, making it suitable for a wide range of applications in this spectral range.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The lens features a standard curve coating on both the front and back surfaces, specifically the EDM NIR-II coating. This coating enhances the lens' performance in the NIR spectrum, providing improved transmission and reduced reflection.
The geometry of the lens includes an edge thickness of 1.86mm and a center thickness of 2.75mm. The effective focal length (EFL) is 44.5mm, and the radius of curvature (R1) is 23mm. The back focal length (BFL) is 42.69mm. The lens does not have an inner or outer radius, indicating a uniform curvature.
