89-042 20.0mm Dia. x 50.0mm FL; Plano-Convex Lens Laser V-Coat 1064nm
The 89-042 is a high-quality plano-convex lens, designed and manufactured by Edmund Optics, a leading provider of optical components. This lens boasts a diameter of 20.0mm and a focal length of 50.0mm, making it suitable for a wide range of applications.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The base shape is circular, and the lens features a plano-convex geometry, which means one side is flat (plano), and the other side is curved (convex). This geometry is often used in optical systems to focus or collimate light.
The lens has a thickness of 1.22mm at the edge and 3.23mm at the center. The effective focal length (EFL) is 50.0mm, and the radius of curvature (R1) is 25.84mm. The back focal length (BFL) is 47.87mm, and both the inner and outer radii are 0mm.
The 89-042 is coated with Edmund Optics' Laser V-Coat 1064, which is specifically designed for use with 1064nm lasers. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it ideal for laser applications.
