84-278 15mm Dia. x 30mm FL Uncoated; UV Plano-Convex Lens
The 84-278 is a 15mm diameter, 30mm focal length uncoated UV plano-convex lens, available from Edmund Optics. This lens is part of the spherical lens family, specifically designed with a plano-convex base shape and circular geometry.
The lens's geometry includes a 1.38mm thickness at the edge, increasing to 3.6mm at the center, with an effective focal length (EFL) of 30mm. The radius of curvature (R1) is 13.75mm, and the back focal length (BFL) is 27.53mm. The lens does not have an inner or outer radius, indicating a flat surface on one side.
The lens is made from fused silica, identified as mal-1965 in the material database. It is designed to work with a wavelength of 587.6nm. The lens's shape is spherical, and it does not have any coatings, as indicated by the empty 'coating' field in the item data.
This lens is suitable for applications that require a simple, uncoated lens with a long focal length. Its uncoated surface may cause some reflection, but it is ideal for use in the ultraviolet region of the spectrum. Please note that the lens's uncoated surface may require additional considerations for applications involving high-intensity light sources or extreme environmental conditions.
