89-414 5mm Dia. x 25mm FL Uncoated; UV Plano-Convex Lens
The 89-414 is a 5mm diameter, 25mm focal length uncoated UV plano-convex lens sourced from Edmund Optics. This lens, identified by its base shape of a circle, is a spherical lens with a plano-convex geometry, meaning one side is flat while the other is curved.
The lens's geometry includes a 1.22mm thickness at the edge and a 1.5mm thickness at the center. The effective focal length (EFL) is 25mm, and the radius of curvature (R1) is 11.46mm. The back focal length (BFL) is 23.97mm, and both the inner and outer radii are 0mm, indicating a flat inner and outer surface.
This lens is made from fused silica material, identified as fused sil mal-1965 in the item data. The wavelength for this lens is 587.6nm. Notably, this lens does not have any coating, as indicated by the empty "coating" field in the item data.
