This is a 65-512 plano-convex lens, a type of spherical lens, sourced from Edmund Optics. The lens has a 6.0mm diameter and a focal length of 24.0mm, designed for use with a wavelength of 785nm. The lens is made from N-BK7 Schott glass, a popular choice for its high homogeneity and excellent transparency in the visible and near-infrared regions.
The lens features a laser-grade V-coat coating on both the front and back surfaces, specifically designed for 785nm. This coating enhances the lens's performance in laser applications, providing improved damage threshold, lower scatter, and better laser beam control.
The geometry of the lens includes a thickness of 1.13mm at the edge and 1.5mm at the center. The lens's effective focal length (EFL) is 24.01mm, and the radius of curvature (R1) is 12.4mm. The back focal length (BFL) is 23.01mm, and the lens has no inner or outer radius, indicating a plano surface on the opposite side of the convex surface.
