L-BCC119 50.8 mm Dia. Double-Concave Lens; EFL=-100mm Uncoated
The L-BCC119 is a spherical lens with a base shape of circular, sourced from the reputable vendor, Ross Optical. This lens falls under the category of a double-concave lens, featuring negative focal length, making it suitable for applications requiring diverging light paths.
The lens has a diameter of 50.8 mm, with a thickness at the edge of 7.59 mm and a center thickness of 2.5 mm. The effective focal length (EFL) is -100 mm, indicating a strong diverging capability. The first radius of curvature (R1) is -104.6372391, and the second radius of curvature (R2) is 104.6372391, both 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. The wavelength for this lens is 587.6 nm. Notably, this lens is uncoated, which may affect its transmission and reflection properties depending on the application.
