L-BCC016 12.5 mm Dia. Double-Concave Lens; EFL=-35mm Uncoated
The L-BCC016 is a spherical lens with a base shape of circular, sourced from the renowned vendor Ross Optical. This lens falls under the category of a bi-concave lens, characterized by its double-concave structure. The lens has a diameter of 12.5 mm and a thickness at the edge of 2.5 mm, while the center thickness measures 1.5 mm.
The effective focal length (EFL) of this lens is -35mm, indicating its diverging nature. The first radius of curvature (R1) is -36.59699728, and the second radius of curvature (R2) is 36.59699728, both measured in millimeters. The lens does not have an inner or outer radius, suggesting a uniform curvature throughout.
The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. It is designed to operate at a wavelength of 587.6 nm. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
