The 69-395 is a Plano-Convex spherical lens, boasting a diameter of 25.0mm and a focal length of 30.0mm, specifically designed for use with a 532nm wavelength. This lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The lens's geometry is meticulously crafted, with an edge thickness of 1.73mm and a center thickness of 8.06mm. The effective focal length (EFL) is 30.0mm, and the radius of curvature (R1) is 15.5mm. The back focal length (BFL) is 24.69mm, and both the inner and outer radii are 0mm.
The lens is constructed from the high-quality material, n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties. The lens's coating is a laser V-coat, specifically designed for 532nm, which enhances its performance and durability. This coating is applied to both the front and back surfaces of the lens.
