The 38-587-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 with a wavelength of 587.6nm. The lens features a front and back coating of YAG-BBAR, specifically designed for the wavelength range of 500-1100nm.
The lens has a thickness of 1.23mm at the edge and 2.2mm at the center. The effective focal length (EFL) of the lens is 40mm, and the radius of curvature (R1) is 20.67mm. The back focal length (BFL) of the lens is 38.55mm. The lens is made of N-BK7 Schott material, a common material in optical applications due to its excellent optical properties.
The YAG-BBAR coating on the lens enhances its durability and performance in the specified wavelength range. This coating reduces reflection and increases transmission, making it ideal for applications that require high transmission and low loss. The lens is inked, which aids in identifying and handling the lens during assembly and use.
