67-942 12mm Dia. x 50mm FL; Laser Grade Plano-Convex Lens Laser V-Coat 266nm
The 67-942 is a laser grade plano-convex lens, boasting a 12mm diameter and a focal length of 50mm, specifically designed for use with a 266nm wavelength. This lens, sourced from Edmund Optics, is a high-quality component, perfect for applications demanding precision and reliability.
The lens is made from fused silica (mal-1965), a material known for its excellent optical properties, making it an ideal choice for laser applications. The plano-convex geometry, with a 2.1mm edge thickness and a 2.9mm center thickness, ensures efficient light transmission and focusing. The inner and outer radii are both zero, indicating a uniform curvature.
The 67-942 features a front and back coating of edm las v-coat 266, a specialized coating that enhances the lens's performance in laser applications. This coating is designed to withstand the rigors of laser use, ensuring the lens maintains its optical properties over time.
The lens's EFL (Effective Focal Length) is 50mm, a crucial specification for determining the lens's focusing power. The BFL (Back Focal Length) is 48.01mm, which is the distance from the back surface of the lens to the focal point.
