47-861 4.0mm Dia. x 4.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm
The 47-861 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. It boasts a diameter of 4.0mm and a focal length of 4.0mm, making it a compact and efficient optical component. The lens is made from n-lasf44 Schott, a material known for its high optical quality.
The lens features a front and back coating of edm vis-0 std curve, which is a standard coating for visible light with a 0-degree angle of incidence. This coating enhances the lens's performance by reducing surface reflections and improving transmission within the 425-675nm wavelength range.
The geometry of the lens is well-defined, with a thickness at the edge of 1.0mm and a center thickness of 1.7mm. The inner and outer radii are both 0mm, indicating a uniform curvature. The lens's effective focal length (EFL) is 4.0mm, and the back focal length (BFL) is 3.06mm. The radius of curvature (R1) is 3.21mm.
The lens is currently in stock and available for immediate purchase through the provided weblink. With its high-quality materials, precise geometry, and advanced coating, the 47-861 is an excellent choice for various optical applications.
