69-610 12.0mm Dia. x 20.0mm FL; Plano-Convex Lens Laser V-Coat 1064nm
This is a 12.0mm diameter x 20.0mm focal length Plano-Convex lens, designed for use with a 1064nm wavelength. The lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The lens geometry includes a 1.58mm thickness at the edge and a 3.5mm thickness at the center, with a 10.34mm radius of curvature on the curved face. The lens has an effective focal length (EFL) of 20mm and a back focal length (BFL) of 17.69mm.
The lens features a laser V-coat coating on both the front and back surfaces, specifically designed for 1064nm. This coating enhances the lens's performance in laser applications, providing improved transmission and reduced reflection. The coating is applied by Edmund Optics using their EDM Las V-Coat process, ensuring high-quality and consistent results.
