The 38-464-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.7mm, is designed for use within the visible light spectrum, specifically optimized for wavelengths of 587.6nm.
The lens features a front and back coating of edm vis ext, which enhances its performance within the specified wavelength range. The lens has a base shape of a circle, with a thickness at the edge of 1.3mm and a center thickness of 2.3mm.
The effective focal length (EFL) of this lens is 40mm, and the radius of curvature (R1) is 20.67mm. The back focal length (BFL) is 38.48mm, and the lens does not have an inner or outer radius.
This lens is made of n-bk7 schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens is in stock and available for immediate purchase, as indicated by its weblink status.
