L-BCC015 12.5 mm Dia. Double-Concave Lens; EFL=-30mm Uncoated
The L-BCC015 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 2.7 mm, while the center thickness measures 1.5 mm.
The effective focal length (EFL) of this lens is -30mm, indicating its diverging nature. The first radius of curvature (R1) is -31.46134047, and the second radius of curvature (R2) is 31.46134047, 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. The wavelength for this lens is 587.6 nm. Notably, this lens is uncoated, which may affect its transmission and reflection properties.
This lens is currently in stock and more information can be found on the Ross Optical website.
