38-283 12.5mm Dia. x 12.5mm FL; VIS 0° Coated; Plano-Convex Lens VIS 0° 425-675nm
The 38-283 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 12.5mm and a focal length of 12.5mm, making it a high-power lens suitable for various applications. The lens is made from n-sf11 Schott, a high-index glass with excellent optical properties.
The lens features a standard coating on both the front and back surfaces, specifically the EDM VIS-0 std curve coating. This coating is designed to provide high transmission in the visible spectrum, ranging from 425 to 675nm. The coating also helps to reduce surface reflections, enhancing the overall efficiency and performance of the lens.
The geometry of the lens includes a thickness of 1.5mm at the edge and 3.75mm at the center. The lens's effective focal length (EFL) is 12.5mm, and the radius of curvature (R1) is 9.81mm. The back focal length (BFL) is 10.4mm, and both the inner and outer radii are 0mm.
