L-BCC110 50 mm Dia. Double-Concave Lens; EFL=-150mm Uncoated

The L-BCC110 is a 50 mm diameter Double-Concave Spherical Lens, featuring a significant EFL (Effective Focal Length) of -150mm. This lens is sourced from Ross Optical, a reputable vendor in the optical industry.

The lens is designed with a base shape of a circle, and its geometry includes a thickness edge of 5.9mm and a thickness center of 2mm. The inner and outer radii are both zero, indicating a uniform curvature throughout the lens. The radii of curvature for the first and second surfaces are -156.0386831mm and 156.0386831mm respectively, suggesting a symmetrical design.

The lens is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The wavelength for this lens is 587.6nm, which is within the visible light spectrum.

Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their performance by reducing reflections, increasing transmission, or providing other desirable optical properties. However, this lens, in its uncoated form, offers a different set of benefits, such as simplicity, cost-effectiveness, and potential compatibility with a wider range of coatings if required in the future.
