47-367 25mm Dia. x 40mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm
The 47-367 is a Double-Convex Lens, a type of Spherical Lens, sourced from Edmund Optics. This lens boasts a base shape of Circular geometry and is designed for use within the visible light spectrum, specifically at a wavelength of 587.6nm. The lens features a diameter of 25mm and a focal length of 40mm, resulting in an f-number of 1.6.
The lens's geometry includes an edge thickness of 1.34mm and a center thickness of 5.3mm. The back focal length (BFL) is 38.21mm, and the effective focal length (EFL) is 40mm. The radii of curvature for the first and second surfaces are 40.42mm and -40.42mm, respectively. The lens does not have an inner or outer radius.
The 47-367 lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens is coated with the EDM VIS-0 STD CURVE coating on both the front and back surfaces, which is designed for visible light with a 0-degree angle of incidence.
This lens is currently in stock and available for immediate purchase from the Edmund Optics website.
