The 88-909-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 30.0mm, 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, a type of coating that is highly reflective in the infrared region and transparent in the visible region, making it ideal for use in a variety of optical applications.
The lens has a thickness of 3.78mm at the edge and 6mm at the center, with an effective focal length (EFL) of 100.0mm. The radius of curvature for the first surface (R1) is 51.68mm, and the back focal length (BFL) is 96.01mm. 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 inked, indicating that it has been marked or labeled for identification purposes. The weblink provided is valid and indicates that the lens is in stock, making it readily available for immediate use.
