The 38-466-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 15.0mm, is designed for use within the visible light spectrum, specifically between 350-700nm. The lens features a front and back coating of edm vis ext, which is a proprietary coating developed by Edmund Optics to enhance the lens's performance within the visible light spectrum.
The lens has a base shape of a circle and a thickness at the edge of 1.4mm, which gradually increases to 3.8mm at the center. The effective focal length (EFL) of the lens is 25.0mm, and the radius of curvature (R1) is 12.92mm. The back focal length (BFL) is 22.5mm, and the lens does not have any inner or outer radius, indicating a plano surface on the incident side.
The lens is made from n-bk7 schott, a popular optical glass due to its excellent optical properties and relatively low cost. This material is known for its low dispersion and high Abbe number, making it an ideal choice for applications that require high image quality and low chromatic aberration.
