This 48-289 UV Plano-Convex Lens, sourced from Edmund Optics, is a spherical lens with a base shape of a circle. It boasts a diameter of 25mm and a center thickness of 3.01mm, with an edge thickness of 2.03mm. The lens has an effective focal length (EFL) of 175mm and a back focal length (BFL) of 172.94mm. The inner and outer radii are both zero, indicating a plano-convex design.
The lens is made from fused silica material, specifically identified as mal-1965 in the material ID. It is designed to operate at a wavelength of 587.6nm. The lens features UV-AR coating on both the front and back surfaces, following the standard curve as specified by Edmund Optics. This coating is designed to work within the UV range, specifically between 250-425nm, making it ideal for UV applications.
