The 38-345-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.0mm, is designed for use in the near-infrared (NIR) spectrum, specifically between 600-1050nm. The lens has a front focal length (FFL) of 50mm, which is the distance from the front surface of the lens to the principal focus.
The lens is made from N-BK7 Schott glass, a common material for optical lenses due to its excellent optical properties and high Abbe number. The lens features a plano-convex geometry, meaning one side is flat (plano) and the other side is curved (convex). The radius of curvature of the curved surface is 25.84mm.
The lens has an edge thickness of 1.19mm and a center thickness of 1.9mm. The back focal length (BFL) is 48.75mm, and the effective focal length (EFL) is 50mm. The lens does not have any inner or outer radius, indicating it is a simple lens without any additional features.
The lens is coated with EDM NIR-I std curve on both the front and back surfaces. This coating enhances the lens's performance in the NIR spectrum by reducing reflection and increasing transmission. The coating status is valid, and the lens is in stock, according to the vendor's website.
