The 48-243-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 40.0mm, is designed for use within the visible light spectrum, specifically at a wavelength of 587.6nm. The lens features a front and back coating of edm vis-0 std curve, providing standard performance and durability.
The lens has a base shape of a circle and a thickness at the edge of 4.03mm, with a center thickness of 5mm. The effective focal length (EFL) of the lens is 400mm, and the radius of curvature (R1) is 206.72mm. The back focal length (BFL) is 396.7mm, and the lens does not have an inner or outer radius.
The lens is made from 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.
