L-BCC029 12.7 mm Dia. Double-Concave Lens; EFL=-100mm Uncoated
The L-BCC029 is a spherical lens with a base shape of a circle, sourced from the renowned optical 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 12.7 mm and a thickness at the edge of 2.81 mm, while the center thickness measures 2.5 mm.
The effective focal length (EFL) of this lens is -100mm, indicating that it is a diverging lens, causing incoming light rays to spread out. The first radius of curvature (R1) is -103.836511, and the second radius of curvature (R2) is 103.836511, both measured in millimeters. The lens does not have an inner or outer radius, suggesting a uniform curvature throughout.
The L-BCC029 lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The wavelength for this lens is 587.6 nm. Notably, this 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 currently in stock and more information about it can be found on the Ross Optical website.
