L-BCC116 50 mm Dia. Double-Concave Lens; EFL=-600mm Uncoated

The L-BCC116 is a 50 mm diameter Double-Concave Spherical Lens, sourced from the renowned optical vendor, Ross Optical. This lens is designed with a base shape of a circle and features a significant double-concave geometry, making it a unique addition to any optical system.

The lens's geometry is characterized by its 50 mm diameter, with a center thickness of 2 mm and an edge thickness of 3 mm. The effective focal length (EFL) is -600mm, indicating that it is a diverging lens, which spreads out light rays. The radii of curvature for the first and second surfaces are -620.6706555 mm and 620.6706555 mm, respectively. The lens does not have an inner or outer radius, indicating a uniform curvature across the lens surface.

The L-BCC116 is made from the high-quality material N-BK7 Schott. This material is known for its excellent optical properties, making it a popular choice for various optical applications. The lens is designed to operate at a wavelength of 587.6 nm.

Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their optical performance by reducing reflection, increasing transmission, or providing other desirable optical properties. However, this lens is designed to function without these enhancements, making it a cost-effective solution for applications where coated lenses are not required.
