69-402 25.0mm Dia. x 250.0mm FL; Plano-Convex Lens Laser V-Coat 532nm
This is a 25.0mm diameter, 250.0mm focal length Plano-Convex lens, specifically designed for use with a 532nm wavelength. The lens is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock.
The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. The base shape of the lens is circular, and it features a Plano-Convex geometry, where one side is flat, and the other side is curved. This particular lens has an inner radius of 0 and an outer radius of 0.
The lens has a thickness of 2.39mm at the edge and 3mm at the center. The effective focal length (EFL) is 250.02mm, and the back focal length (BFL) is 248.02mm. The radius of curvature (R1) is 129.2mm.
The lens is coated with Edmund Optics' Las V-Coat 532, a specialized coating designed for laser applications at a 532nm wavelength. This coating ensures high transmission and low reflection, making it ideal for laser systems.
