L-BCC013 25 mm Dia. Double-Concave Lens; EFL=-25mm Uncoated

The L-BCC013 is a 25 mm diameter Double-Concave Spherical Lens, featuring a negative focal length (EFL) of -25mm, making it suitable for applications that require light to be diverged. This lens is sourced from Ross Optical, a reputable vendor known for their high-quality optical elements.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number, ensuring low dispersion and high homogeneity. The lens geometry includes an edge thickness of 8.1mm and a center thickness of 2mm, providing robustness and stability.

The lens's base shape is circular, allowing for versatile use in various optical systems. The inner and outer radii are both zero, indicating a symmetrical curvature. The radii of curvature, R1 and R2, are -27.15317065mm and 27.15317065mm respectively, suggesting a strongly converging then diverging effect.

The lens is uncoated, which may be desirable for applications where the natural properties of the glass are preferred, or where cost-effectiveness is a priority. However, it's important to note that uncoated lenses can suffer from reduced transmission and increased susceptibility to environmental factors.
