LB4910-UV 50.8 mm Dia. UVFS Double-Convex Lens; EFL=500mm 245-400nm
The LB4910-UV is a high-quality double-convex lens, boasting a 50.8 mm diameter and a focal length of 500mm. This lens is specifically designed for use in the ultraviolet spectrum, with a wavelength range of 245-400nm, making it an ideal choice for applications requiring precise UV light manipulation.
This lens is sourced from Thorlabs, a trusted name in the optical components industry, and is crafted from UVFS, a material with excellent transparency in the UV range. The lens features a UV-coated front and back surface, further enhancing its performance in UV applications. The coating, identified as "tho uvfs uv bbar," is a broadband antireflection coating designed for use in the UV range.
The lens geometry is spherical, with a center thickness of 4.4mm and an edge thickness of 3mm. The radii of curvature for the front and back surfaces are 459.4mm and -459.4mm, respectively. The lens has no inner or outer radius, indicating a uniform curvature across the entire surface.
