The 36-712 is a UV-VIS coated plano-convex lens, boasting an 18mm diameter and a 54mm focal length. This lens, sourced from Edmund Optics, is a spherical lens with a base shape of a circle, designed for use within the ultraviolet and visible light spectrum, specifically between 250 and 700 nanometers.
The lens's geometry is meticulously crafted, with a thickness at the edge of 1.81mm and a center thickness of 3.5mm. The effective focal length (EFL) is 54mm, and the radius of curvature (R1) is 24.76mm. The back focal length (BFL) is 51.6mm, and both the inner and outer radii are 0mm, indicating a flat surface.
The lens is made from fused silica, identified as mal-1965 in the Material ID. This material is known for its excellent transmission properties and chemical resistance, making it ideal for applications in harsh environments.
The lens features a standard UV-VIS coating on both the front and back surfaces, following the Edmund Optics' UV-VIS standard curve. This coating enhances the lens's performance by reducing surface reflections and increasing transmission within the specified wavelength range.
