BF-px-50.8-254 50.8 mm Dia. BaF2 Plano-Convex Lens; EFL=254mm Uncoated
This is the BF-px-50.8-254, a 50.8 mm diameter Plano-Convex lens made from BaF2 (Barium Fluoride) material. The lens is sourced from Alkor Technologies and is currently in stock, as indicated by its valid weblink status.
The lens features a spherical shape, with a large radius of curvature (r1) of 112.72 mm. It has an outer radius of 0 mm, indicating a planar surface on one side. The lens's thickness at the edge is 2.5 mm, while the center thickness is 5.4 mm. The effective focal length (EFL) of this lens is 254 mm.
The lens is uncoated, which means it does not have any anti-reflective or other coatings applied to its surfaces. This could result in higher reflective losses and lower transmission, especially at shorter wavelengths. However, it also means that the lens is less susceptible to damage from environmental factors or handling.
The lens is made from BaF2, a high-quality optical material known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum. It has a wide transmission range, making it suitable for various applications, including UV and IR imaging, beam shaping, and laser systems.
