67-955 25mm Dia. x 75mm FL; Laser Grade Plano-Convex Lens Laser V-Coat 355nm
The 67-955 is a laser grade plano-convex lens, boasting a 25mm diameter and a 75mm focal length. This lens, sourced from Edmund Optics, is designed for use with a 355nm 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 2.08mm edge thickness and a 4.43mm center thickness. Its base shape is circular, and the spherical surface has a 34.39mm radius. The back focal length measures 71.96mm, and the effective focal length is 75mm. The lens's inner and outer radii are both 0mm, indicating a uniform curvature.
The lens is made from fused silica (mal-1965), a material known for its excellent optical properties and durability. The laser V-coat on both surfaces enhances the lens's performance by reducing reflections and increasing transmission at the 355nm wavelength.
