88-919-INK 50.0mm Dia. x 75.0mm FL; YAG-BBAR; Inked; Plano-Convex Lens YAG-BBAR 500-1100nm
The 88-919-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 50.0mm, is designed for use in the visible light spectrum, specifically at a wavelength of 587.6nm. The lens features a front and back coating of YAG-BBAR, which is optimized for use within the wavelength range of 500-1100nm.
The lens's geometry is characterized by a thickness of 1.86mm at the edge and 11mm at the center. The effective focal length (EFL) is 75.0mm, and the radius of curvature (R1) is 38.76mm. The back focal length (BFL) is 67.75mm, and both the inner and outer radii are 0mm. The lens is made of N-BK7 Schott material, a common type of glass used in optical applications due to its excellent optical properties.
The YAG-BBAR coating on the lens enhances its durability and performance. This coating reduces reflection and increases transmission, making it ideal for use in high-power laser applications. The lens is inked, which aids in identifying and tracking the lens during assembly and use.
