LD4103 25.4 mm Dia. UVFS Double-Concave Lens; EFL=-100mm Uncoated
The LD4103 is a spherical lens from Thorlabs, featuring a unique double-concave design with a base shape of a circle. This lens has a diameter of 25.4 mm and a center thickness of 3.5 mm. The effective focal length (EFL) of this lens is -100mm, making it a powerful tool for optical systems that require strong negative lensing.
The lens is made from UVFS material with the ID MAL-1965. The radii of curvature for this lens are -92.6 mm for the first surface and 92.6 mm for the second surface. The inner and outer radii are both 0, indicating a uniform curvature throughout the lens.
The LD4103 is designed to operate at a wavelength of 587.6 nm. It does not come with any coating, which means it is uncoated. This may affect its performance in certain applications, particularly those requiring high transmission or resistance to environmental factors.
