This is a BICX-12.7/25.4UV lens, a high-quality optical component sourced from Laser Components. The lens is a spherical type, specifically a double-convex lens, with a base shape of a circle. It has a diameter of 12.7 mm and a thickness at the edge of 2 mm, while the center thickness is 3.6 mm. The effective focal length (EFL) of this lens is 25 mm.
The lens features inner and outer radii of 0 mm, and its first and second radii of curvature (R1 and R2) are 25.4 mm and -25.4 mm respectively, indicating its double-convex shape. The lens is made of fused sil mal-1965, a material known for its excellent optical properties.
This lens is designed to operate at a wavelength of 248 nm. It does not have any coating, which means it is uncoated. The lens's uncoated state can be suitable for specific applications where coating might introduce unwanted reflections or alter the optical properties.
