The LD4103-UV is a Spherical Lens with a Sub Type of Spherical Lens (Concave-Concave), boasting a Base Shape of Circular. This lens, sourced from the reputable vendor Thorlabs, has a diameter of 25.4 mm and a center thickness of 3.5 mm. The Effective Focal Length (EFL) is -100.3mm, indicating a double-concave design.
The lens is made from UVFS material with the ID 1965, and it is designed to work with a wavelength of 588nm. The lens features a UV-optimized broadband anti-reflection coating, denoted as "tho uvfs uv bbar" on both the front and back surfaces. This coating enhances transmission in the UV range, typically from 245 to 400nm.
The lens's geometry includes an inner radius of 0 and an outer radius of 0, suggesting a symmetrical design. The lens's concave-concave shape, indicated by the radii of curvature r1 (-92.6) and r2 (92.6), contributes to its unique optical properties.
