45-381 9.0mm Dia. x -18 FL; MgF2 Coated; Plano-Concave Lens 400-700nm
The 45-381 is a plano-concave lens with a 9.0mm diameter, offering a focal length of -18 and a central thickness of 2.25. The lens is sourced from Edmund Optics, a reputable vendor in the optical industry, and is currently in stock.
This lens is made from n-sf11 Schott, a high-index glass with excellent transmittance in the visible spectrum, making it ideal for applications within the 400-700nm range. The lens's geometry includes an inner radius of 0 and an outer radius of 0, indicating a simple spherical shape.
The 45-381 is coated with MgF2, a standard coating that provides high transmission across the visible spectrum. This coating is applied to both the front and back surfaces of the lens, ensuring optimal performance.
The lens's base shape is circular, and its geometry includes a thickness edge of 2.89. The BFL (back focal length) is -19.26, and the R1 (radius of curvature) is -14.12.
