49-973 20mm Dia. x 40mm FL UV-VIS Coated; UV Plano-Convex Lens UV-VIS 250-700nm
The 49-973 is a UV-VIS coated Plano-Convex lens, sourced from the reputable optical vendor, Edmund Optics. This lens boasts a 20mm diameter and a 40mm focal length, making it suitable for a wide range of optical applications.
The lens is crafted from fused sil mal-1965, a material known for its excellent optical properties. The base shape of the lens is circular, and it features a spherical geometry, with a 1.53mm edge thickness and a 4.5mm center thickness. The inner and outer radii are both zero, indicating a uniform curvature.
The 49-973 lens is coated with the EDM UV-VIS std curve on both the front and back surfaces. This coating enhances the lens's performance within the UV-VIS spectrum, specifically between 250-700nm. The coating ensures optimal light transmission and reduces surface reflections, making it an ideal choice for applications that require high-quality imaging or light transmission.
In terms of its optical parameters, the lens has a 36.92mm back focal length and an 18.34mm radius of curvature. The effective focal length is 40mm, which is a common choice for many optical systems due to its versatility.
