The 67-585-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 50.0mm, is designed for use in the near-infrared (NIR) spectrum, specifically 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 range.
The lens has a thickness of 1.86mm at the edge and 11mm at the center, providing a base shape that is circular. The effective focal length (EFL) of this lens is 75mm, and the radius of curvature (R1) is 38.76mm. The back focal length (BFL) is 67.75mm, 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 inked, which is a process that adds a dye to the lens to make it easier to handle and identify.
