The 88-968 is a Plano-Convex spherical lens, boasting a 5.0mm diameter and a 25.0mm focal length, specifically designed for use with a 405nm wavelength. This lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The lens is made from n-BK7 Schott, a high-quality optical glass, and features a Laser V-Coat 405nm coating on both the front and back surfaces. This coating enhances the lens's performance in laser applications, providing improved transmission and reduced reflection.
The geometry of the lens is meticulously designed, with a thickness of 1.36mm at the edge and 1.6mm at the center. The lens's effective focal length (EFL) is 25mm, and its radius of curvature (R1) is 12.92mm. The back focal length (BFL) is 23.95mm, and both the inner and outer radii are 0mm.
This lens is circular in base shape and is an excellent choice for various applications due to its high-quality construction, precise geometry, and superior coating.
