The 67-967 is a laser grade plano-convex lens, boasting a 25mm diameter and a 150mm focal length. This lens, sourced from Edmund Optics, is designed for use with a 532nm wavelength and features a high-quality laser V-coat on both the front and back surfaces.
The lens's geometry is optimized for laser applications, with a 2.04mm edge thickness and a 3.18mm center thickness. Its effective focal length (EFL) is 150mm, and the radius of curvature (R1) on the curved face is 68.79mm. The back focal length (BFL) is 147.82mm, and both the inner and outer radii are 0mm, indicating a flat back surface.
The lens is crafted from fused silica, a material with the material ID "fused sil mal-1965". This material is known for its excellent transmission properties, making it ideal for use in laser systems.
The front and back surfaces of the lens are coated with Edmund Optics' laser V-coat, designed specifically for 532nm. This coating enhances the lens's performance in laser applications, reducing reflections and improving transmission.
