L-BCC122 50.8 mm Dia. Double-Concave Lens; EFL=-250mm Uncoated
The L-BCC122 is a spherical lens with a base shape of circular and a subtype of double-concave. This lens, sourced from Ross Optical, is designed for use in optical systems that require concave-concave geometry. The lens has a diameter of 50.8 mm and a thickness at the edge of 4.52 mm, while the center thickness is 2.5 mm.
The effective focal length (EFL) of this lens is -250mm, indicating that it is a diverging lens, which spreads out light rays. The first radius of curvature (R1) is -259.16774 mm, and the second radius of curvature (R2) is 259.16774 mm. The lens does not have an inner or outer radius, indicating a uniform curvature throughout.
The lens is made of N-BK7 Schott glass, a common material in optical systems due to its excellent optical properties and high Abbe number. The wavelength for this lens is 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.
This lens is in stock and more information can be found on the Ross Optical website.
