The 38-632 is a 25.4mm diameter, 500mm focal length plano-convex spherical lens, manufactured by Edmund Optics. This uncoated lens is crafted from UVFS material, specifically identified as Mal-1965, and optimized for a wavelength of 587.6nm.
The lens's base shape is circular, with a 3.63mm edge thickness and a 4mm center thickness. Its effective focal length (EFL) is 500mm, and the radius of curvature (R1) is 238.04mm. The back focal length (BFL) measures 497.44mm, while both the inner and outer radii are 0mm.
This lens is designed for laser applications, boasting high-quality, precision-ground surfaces for optimal performance. The uncoated version offers excellent value for applications where anti-reflection coatings are not required. However, for applications demanding lower surface reflectance, Edmund Optics offers a variety of anti-reflection coatings that can be applied to this lens.
