The 38-671 is a laser grade plano-convex lens, designed and manufactured by Edmund Optics, a leading provider of optical components. This lens boasts a diameter of 25.4mm and a focal length of 35mm, making it suitable for a wide range of applications that require high-precision optics.
The lens is constructed from UVFS, a material with a refractive index of 1.965, which is specifically designed for use in the ultraviolet spectrum. This makes the lens ideal for use in applications involving 355nm wavelength lasers.
The lens features a plano-convex geometry, with a flat front surface and a curved back surface. The radius of curvature of the back surface is 16.66mm, and the lens has a back focal length of 28.55mm. The lens has a central thickness of 9.53mm and an edge thickness of 3.04mm, providing excellent optical performance and durability.
The lens is coated with Edmund Optics' Laser V-Coat 355, a proprietary coating designed to enhance the lens' performance in laser applications. This coating provides high transmission at the design wavelength, as well as excellent environmental stability and resistance to laser damage.
