L-BCC051 25 mm Dia. Double-Concave Lens; EFL=-40mm Uncoated

The L-BCC051 is a 25 mm diameter Double-Concave Spherical Lens, sourced from the renowned optical component vendor, Ross Optical. This lens is designed with a base shape of a circle and features a unique double-concave geometry, making it an ideal choice for specific optical applications.

The lens's geometry is characterized by its diameter of 25 mm, with a center thickness of 1.5 mm and an edge thickness of 5.3 mm. The effective focal length (EFL) of this lens is -40 mm, indicating its diverging nature. The first radius of curvature (R1) is -42.22799955 mm, and the second radius of curvature (R2) is 42.22799955 mm, further emphasizing its double-concave design. The lens does not have an inner or outer radius, indicating a uniform curvature throughout.

The L-BCC051 is made from the high-quality material N-BK7 Schott. This material is known for its excellent optical properties, making it a popular choice in various optical applications. The lens is designed to operate at a wavelength of 587.6 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 optical properties, such as reducing reflection, increasing transmission, or protecting the lens surface. However, the uncoated nature of the L-BCC051 may be advantageous in certain applications where specific coating characteristics are not required.
