The 67-575-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 40.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750 and 1550nm.
The lens features a front and back coating of edm nir-ii std curve, which enhances its performance in the NIR II spectrum. The lens has a thickness of 3.78mm at the edge and 6mm at the center, providing a base shape that is circular.
The effective focal length (EFL) of this lens is 100mm, and its radius of curvature (R1) is 51.68mm. The back focal length (BFL) is 96.01mm, and the lens does not have an inner or outer radius.
This lens is made of n-bk7 schott, a material known for its excellent optical properties. The lens is in stock and available for immediate purchase, as indicated by its weblink status.
