48-035 12mm Dia. x 20mm FL; Uncoated; UV Double-Convex Lens
The 48-035 is a 12mm diameter, uncoated, UV double-convex lens with a focal length of 20mm, sourced from the reputable optical components vendor, Edmund Optics. This lens is a spherical lens of the convex-convex type, featuring a base shape that is circular.
The lens's geometry is meticulously designed, with a thickness of 2.27mm at the edge and 4.37mm at the center. The effective focal length (EFL) is 20mm, and the radii of curvature are 17.63mm for the first surface and -17.63mm for the second surface. The back focal length (BFL) is 18.44mm. The lens does not have any inner or outer radius, indicating a uniform curvature throughout.
The lens is made from fused silica material, identified as mal-1965 in the material database. It is designed to operate at a wavelength of 587.6nm. The lens's shape is spherical, and it does not have any coating, which is indicated by the empty 'coating' parameter in the item data.
This lens is a versatile optical component, suitable for various applications that require a double-convex lens with a UV transmission capability. Its uncoated surface provides a bare, pure optical path, making it ideal for applications where minimal reflection and dispersion are required.
