9mm Diameter x 27mm UV-VIS Coated Double-Convex Lens by Edmund Optics
This is a 9mm diameter x 27mm thick double-convex lens, manufactured by Edmund Optics. The lens is UV-VIS coated, indicating that it has anti-reflective coatings optimized for the ultraviolet (UV) and visible (VIS) regions of the spectrum, specifically designed for use between 250-700nm.
The lens is made of fused silica, a type of glass known for its excellent transmission properties, high mechanical strength, and chemical resistance. The base shape of the lens is circular, and it has a spherical geometry, meaning both surfaces are portions of spheres.
The first radius of curvature (R1) is 24.36mm, and the second radius of curvature (R2) is -24.36mm, indicating that the lens is a meniscus lens with the center being thicker than the edges. The effective focal length (EFL) of the lens is 27mm, and the back focal length (BFL) is 26.13mm.
The lens has a center thickness of 2.5mm and an edge thickness of 1.66mm. The inner radius is 0mm, and the outer radius is also 0mm, suggesting that the lens has a uniform thickness.
This lens is suitable for applications that require high-quality imaging or light control in the UV-VIS range, such as UV-VIS spectroscopy, fluorescence microscopy, or other applications where UV or visible light needs to be focused or manipulated.
