The 88-847-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.7mm, is designed for use in the visible light spectrum, specifically at a wavelength of 587.6nm. The lens features a front and back coating of YAG-BBAR, which is optimized for use within the 500-1100nm range.
The lens has a thickness of 1.36mm at the edge and 3mm at the center, providing a base shape that is circular. The effective focal length (EFL) of the lens is 25.4mm, and the radius of curvature (R1) is 13.13mm. The back focal length (BFL) is 23.43mm, and both the inner and outer radii are 0mm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. This lens is in stock, as indicated by its weblink status, making it readily available for your optical needs.
