67-540 20.0mm Dia. x 100.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-540 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 20.0mm and a focal length of 100.0mm, making it a versatile choice for various optical applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a front and back coating of EDM NIR-II STD Curve, a specialized coating designed for use in the near-infrared (NIR) spectrum, specifically between 750-1550nm. This coating enhances the lens's performance in the NIR range, improving transmission and reducing reflection.
The geometry of the lens includes a thickness edge of 2.84mm and a thickness center of 4.5mm. The lens's effective focal length (EFL) is 60mm, and its radius of curvature (R1) is 31.01mm. The back focal length (BFL) is 57.03mm, and both the inner and outer radii are 0mm.
According to the vendor's website, the lens is currently in stock, making it a readily available option for those in need of a high-quality, NIR-optimized Plano-Convex lens.
