67-958 25mm Dia. x 250mm FL; Laser Grade Plano-Convex Lens Laser V-Coat 355nm
The 67-958 is a laser grade plano-convex lens, boasting a diameter of 25mm and a focal length of 250mm, specifically designed for use with a wavelength of 355nm. This lens, sourced from the reputable vendor Edmund Optics, is a high-quality component intended for advanced optical applications.
The lens is constructed from fused silica, a material with the material ID 'mal-1965'. This material is known for its excellent transparency and durability, making it an ideal choice for laser applications. The lens features a plano-convex geometry, meaning one side is flat (plano) and the other side is curved (convex). This particular lens has an inner radius of 0 and an outer radius of 0, suggesting a symmetrical curvature.
The 67-958 lens has a thickness of 2.03mm at the edge and 2.71mm at the center. The effective focal length (EFL) is 250mm, and the radius of curvature (R1) is 114.61mm. The back focal length (BFL) is 248.14mm.
The lens is coated with Edmund Optics' Laser V-Coat 355, a specialized coating designed for use with 355nm lasers. This coating enhances the lens' performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.
