The 47-857-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 5.0mm, is designed for use in the visible to near-infrared spectrum, specifically between 400-1000nm. The lens has a front and back coating of edm visnir0sp2002000, which is ideal for applications within this spectral range.
The lens's geometry includes a thickness edge of 1.0mm and a thickness center of 1.87mm. The effective focal length (EFL) is 5.0mm, and the radius of curvature (R1) is 4.02mm. The back focal length (BFL) is 3.96mm, and both the inner and outer radii are 0mm. The lens is made from n-lasf44 schott, a material known for its excellent optical properties.
The lens's coating and material make it suitable for a wide range of applications, including but not limited to, imaging, beam shaping, and light collimation. The lens is in stock and available for immediate purchase, as indicated by the "weblink status" field in the item data.
