84-240 12.0mm Dia. x 15.0mm FL; Plano-Convex Lens Laser V-Coat 1550nm
The 84-240 is a Plano-Convex spherical lens, part of Edmund Optics' extensive catalog of optical elements. This lens boasts a 12.0mm diameter and a 15.0mm focal length, making it suitable for a wide range of applications.
The lens is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The base shape is circular, and the lens features a plano-convex geometry, where one side is flat, and the other side is curved.
The lens has a thickness of 1.66mm at the edge and 4.5mm at the center. The effective focal length (EFL) is 15mm, and the radius of curvature (R1) is 7.75mm. The back focal length (BFL) is 12.03mm, and both the inner and outer radii are 0mm.
The 84-240 is coated with Edmund Optics' Las V-Coat 1550, a specialized coating designed for use with a 1550nm wavelength. This coating enhances the lens' performance by reducing reflection and increasing transmission, making it ideal for laser applications.
The lens is currently in stock and available for purchase through the Edmund Optics website. For more information, including technical specifications and pricing, please refer to the provided weblink.
