88-975 20.0mm Dia. x 60.0mm FL; Plano-Convex Lens Laser V-Coat 405nm
The 88-975 is a high-quality Plano-Convex spherical lens, sourced from the renowned optical vendor, Edmund Optics. This lens boasts a 20.0mm diameter and a 60.0mm focal length, making it suitable for a wide range of optical applications.
The lens is crafted from the esteemed N-BK7 Schott glass, a material known for its excellent optical properties, including high transmission in the visible spectrum and low auto-fluorescence. The base shape of the lens is circular, contributing to its versatility in various optical systems.
The geometry of the lens is meticulously designed, with a thickness of 2.84mm at the edge and 4.5mm at the center. The effective focal length (EFL) is 60mm, and the radius of curvature (R1) is 31.01mm. The back focal length (BFL) is 57.03mm, and both the inner and outer radii are 0mm, indicating a plano surface on the back side of the lens.
The lens features a broadband anti-reflection coating, specifically designed for 405nm. This coating, known as Edmund Optics Las V-Coat 405, ensures high transmission and low reflectance across the specified wavelength range. The coating is applied to both the front and back surfaces of the lens, enhancing its performance in laser applications.
