69-483 10.0mm Dia. x 40.0mm FL; Plano-Convex Lens Laser V-Coat 785nm
The 69-483 is a high-quality Plano-Convex spherical lens, boasting a 10.0mm diameter and a 40.0mm focal length. This lens is sourced from the renowned optical vendor, Edmund Optics, and is designed to work optimally with a wavelength of 785nm.
The lens is crafted from the esteemed N-BK7 glass from Schott, a material known for its excellent optical properties. The base shape of the lens is circular, and it features a front surface that is plano, meaning it is flat, while the rear surface is convex, curving outward.
The lens has a thickness of 2.39mm at the edge and 3mm at the center. The effective focal length (EFL) is 40mm, and the radius of curvature (R1) is 20.67mm. The back focal length (BFL) is 38.02mm, and both the inner and outer radii are 0mm.
The 69-483 is equipped with a front and back coating of EDM Las V-Coat 785, a specialized coating designed to enhance the lens' performance in laser applications. This coating ensures high transmission and low reflection, making it ideal for use in laser systems.
