L-BCC085 38.1 mm Dia. Double-Concave Lens; EFL=-50mm Uncoated

The L-BCC085 is a 38.1 mm diameter Double-Concave Spherical Lens, sourced from the renowned optical vendor, Ross Optical. This lens is designed with a base shape of Circular geometry, making it a versatile choice for various optical applications.

The lens features a significant double-concave design, with an inner radius of 0 and an outer radius of 0. The first radius (R1) is -53.05727247, and the second radius (R2) is 53.05727247, demonstrating the concave-concave nature of the lens. The lens's thickness at the edge is 8.3, while the center thickness is 2.5, providing a sleek and compact design.

The Effective Focal Length (EFL) of this lens is -50mm, indicating that it is a diverging lens. This makes it ideal for applications that require light to be spread out, such as in projectors or other imaging systems.

The lens is made from the high-quality material N-BK7 Schott, a borosilicate glass known for its excellent optical properties. This material is particularly suitable for use in the visible spectrum, with a wavelength of 587.6 nm.

Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections, increasing transmission, or providing other benefits, an uncoated lens can be a cost-effective choice for applications where such enhancements are not required.
