LB5552 25.4 mm Dia. CaF2 Double-Convex Lens; EFL=100mm Uncoated

The LB5552 is a high-quality spherical lens with a base shape of a circle, boasting a diameter of 25.4 mm and a double-convex design. This lens is sourced from the reputable vendor, Thorlabs. The lens's geometry includes a thickness of 2 mm at the edge and 3.9 mm at the center, with an effective focal length (EFL) of 100 mm, making it suitable for a wide range of optical applications.

The lens is crafted from Calcium Fluoride (CaF2) with the material ID mal-1963. This material is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum. The LB5552 is designed to operate at a wavelength of 588 nm.

Notably, this lens does not come with any coating, as indicated in the item data. Coatings are often applied to lenses to enhance their performance by reducing reflection, increasing transmission, or providing protection against environmental factors. However, the uncoated nature of the LB5552 may be advantageous in certain applications where specific coating characteristics are not required.
