48-347 12mm Dia. x -18 FL; VIS-NIR Coated; Plano-Concave Lens 400-1000nm
The 48-347 is a Plano-Concave Spherical Lens with a 12mm diameter, sourced from the renowned optical components vendor, Edmund Optics. This lens is designed for use within the Visible to Near-Infrared (VIS-NIR) spectrum, specifically catering to wavelengths between 400-1000nm.
The lens features a base shape of a circle and has a thickness of 4.7mm at the edge, reducing to 3.5mm at the center. The effective focal length (EFL) is -18, making it a concave lens. The first radius of curvature (R1) is -14.12, and the back focal length (BFL) is -19.95. The lens does not have an inner or outer radius.
The lens is made from n-SF11 Schott, a high-index glass with excellent transmittance in the VIS-NIR range. It is coated with EDM VISNIR0SP2002000 on both the front and back surfaces, enhancing its performance within the VIS-NIR spectrum.
