The 88-846-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 YAG-BBAR coating on both the front and back surfaces. This coating, which stands for Yttrium Aluminum Garnet - Broad Band Anti-Reflection, is designed to reduce reflection and increase transmission of light over a broad spectrum, in this case, from 500nm to 1100nm.
The lens has a thickness of 1.69mm at the edge and 4mm at the center. The effective focal length (EFL) of the lens is 19.1mm, and the radius of curvature (R1) is 9.87mm. The back focal length (BFL) is 16.46mm, and the lens does not have an inner or outer radius.
The lens is made of N-BK7 Schott, a common optical glass with excellent optical properties. This lens is in stock and available for immediate purchase, making it a reliable choice for your optical needs.
