48-686 25.0mm Dia. x -35 FL; MgF2 Coated; Plano-Concave Lens 400-700nm
The 48-686 is a plano-concave lens with a diameter of 25.0mm, a focal length of -35, and a central thickness of 3.5mm. The edge thickness measures 6.36mm. This lens is sourced from Edmund Optics and is currently in stock.
The lens is made from n-sf11 Schott, a high-index glass with excellent transmittance in the visible spectrum, making it suitable for applications that require high light transmission within the 400-700nm range. The lens's base shape is circular, and its geometry is spherical, with an inner radius of 0mm and an outer radius of 0mm.
The lens features a front and back coating of edm mgf2 std curve. This MgF2 coating is a standard broadband anti-reflection coating that provides high transmission across the visible spectrum. It reduces reflection and increases the lens's overall light transmission, making it ideal for use in imaging systems, beam shaping, and other applications that require high-quality optical components.
