47-857 5.0mm Dia. x 5.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 47-857 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 5mm and a focal length of 5mm, making it a compact yet powerful optical component. The lens is made from the material n-lasf44 schott, a detail that could be crucial for users looking for specific material properties.
The lens features a front and back coating of edm visnir0sp2002000, a VIS-NIR coating suitable for the wavelength of 587.6nm. This coating enhances the lens's performance in the visible to near-infrared spectrum, spanning 400-1000nm. The coating ensures high transmission and low reflection, making it ideal for applications that require high-quality imaging or light transmission.
The geometry of the lens is also noteworthy. It has a thickness of 1mm at the edge and 1.87mm at the center, providing a balanced profile for various optical applications. The inner and outer radii are both 0, indicating a flat surface on the lens's non-curved side. The curvature of the lens is defined by a radius of 4.02mm on the curved side, and the back focal length is 3.96mm.
