36-697 12mm Dia x 84mm FL UV-AR Coated; UV Plano-Convex Lens UV-AR 250-425nm
The 36-697 is a UV Plano-Convex Lens, 12mm in diameter and 84mm in focal length, featuring UV-AR coating on both surfaces. This lens, sourced from Edmund Optics, is designed for use within the UV spectrum, specifically between 250-425nm. Its plano-convex geometry, with a base shape of circular, offers a range of benefits, including a large clear aperture and minimal spherical aberration.
The lens has a diameter of 12mm, with a thickness of 2.03mm at the edge and 2.5mm at the center. The effective focal length (EFL) is 84mm, and the radius of curvature (R1) is 38.51mm. The back focal length (BFL) is 82.28mm, and the lens does not have an inner or outer radius. The material used for this lens is fused sil mal-1965, a material known for its excellent transmission properties in the UV range.
The lens features a standard UV coating on both the front and back surfaces, following the EDUM UV STD CURVE. This coating enhances the lens's performance by reducing surface reflections and increasing transmission within the specified UV range. The coating also provides protection against environmental factors, ensuring the lens maintains its performance over time.
