This product is a Plano-Convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified with the code 48-247-INK, is a spherical lens with a base shape of a circle. It is designed for use within the visible light spectrum, specifically optimized for a wavelength of 587.6nm.
The lens has a diameter of 50.0mm and a thickness at the edge of 4.97mm. The center thickness is 10mm, and the effective focal length (EFL) is 125.0mm. The radius of curvature for the first surface (R1) is 64.6mm, and the back focal length (BFL) is 118.39mm. 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's front and back surfaces are coated with the EDM VIS-0 standard curve coating, which is designed to enhance its performance within the visible light spectrum (425-675nm).
The lens's current status is in stock, and more information can be found on the Edmund Optics website at https://www.edmundoptics.com/f/vis-0-coated-plano-convex-pcx-lenses/12964/.
