69-415 6.0mm Dia. x 7.5mm FL; Plano-Convex Lens Laser V-Coat 633nm

The 69-415 is a Plano-Convex spherical lens, boasting a 6.0mm diameter and a focal length of 7.5mm, specifically designed for use with a 633nm wavelength. This lens is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.

The lens is constructed from n-sf11 Schott material, a popular choice for its high refractive index and low dispersion properties. The front and back surfaces of the lens are coated with Edmund Optics' Las V-Coat 633, a specialized coating that enhances laser damage threshold and transmission at the specified wavelength.

The lens's geometry is meticulously designed, with an edge thickness of 1.68mm and a center thickness of 2.5mm. The effective focal length (EFL) is 7.5mm, and the radius of curvature for the first surface (R1) is 5.89mm. The back focal length (BFL) is 6.1mm, and both the inner and outer radii are 0mm, indicating a flat back surface.
