48-692 25mm Dia. x -35 FL; VIS 0deg Coated; Plano-Concave Lens 425-675nm
The 48-692 is a 25mm diameter Plano-Concave Spherical Lens with a focal length of -35, sourced from Edmund Optics. This lens is designed for use within the visible light spectrum, specifically between 425-675nm. The lens features a standard coating on both the front and back surfaces, optimized for 0-degree angle of incidence (VIS 0deg Coated).
The lens's geometry includes a diameter of 25mm, with a center thickness of 3.5mm and an edge thickness of 6.36mm. The inner radius is 0mm, and the outer radius is also 0mm. The back focal length (BFL) is -36.96mm, and the effective focal length (EFL) is -35mm.
This lens is made from n-sf11 Schott material, a lead-silicate glass known for its high refractive index and low dispersion. The standard coating on both surfaces enhances the lens's performance within the specified wavelength range.
