49-983 6mm Dia. x 18mm FL; Uncoated; UV Double-Convex Lens
The 49-983 is a 6mm diameter, 18mm focal length uncoated UV double-convex lens, sourced from the reputable optical vendor, Edmund Optics. This lens is a spherical lens with a convex-convex base shape, contributing to its double-convex design. Its circular geometry, with a thickness of 1.44mm at the edge and 2mm at the center, is complemented by an effective focal length (EFL) of 18mm.
The lens's inner and outer radii are both zero, indicating a symmetrical design. The first radius of curvature (R1) is 16.18mm, while the second radius of curvature (R2) is -16.18mm, further emphasizing its double-convex nature. The back focal length (BFL) is 17.3mm.
This lens is crafted from fused silica, specifically the variant with the material ID 1965. It is designed to operate at a wavelength of 587.6nm. The lens does not come with any coating, as indicated by the empty 'coating' field in the item data.
