The 67-537-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 20.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically between 750-1550nm. The lens features a front and back coating of edm nir-ii std curve, which enhances its performance in the NIR II range.
The lens has a thickness of 1.48mm at the edge and 4.5mm at the center, providing a base shape that is circular. The effective focal length (EFL) of this lens is 35mm, and the radius of curvature (R1) is 18.09mm. The back focal length (BFL) is 32.04mm, and the lens does not have an inner or outer radius.
The lens is made from n-bk7 schott, a material known for its excellent optical properties. The wavelength for this lens is 587.6nm. The lens is in stock and available for immediate purchase, as indicated by its weblink status.
