L-BCX015 12.7 mm Dia. Double-Convex Lens; EFL=50.2mm Uncoated

The L-BCX015 is a spherical lens with a base shape of circular, sourced from the renowned optical vendor, Ross Optical. This lens is a double-convex type, featuring two convex surfaces that are curved outwards. The lens has a diameter of 12.7 mm and a thickness at the edge of 3 mm, while the center thickness measures 3.79 mm.

The lens's effective focal length (EFL) is 50.2 mm, which is the distance from the lens's center to the focal point when the lens is focused at infinity. The first radius of curvature (R1) is 51.23 mm, and the second radius of curvature (R2) is -51.23 mm, indicating that the lens's curvature is symmetrical.

The lens is made of n-BK7 Schott material, a common type of optical glass known for its excellent optical properties. The wavelength for this lens is 587.6 nm. Notably, this lens does not have any coating, which means it is uncoated. Coatings are often applied to lenses to reduce reflection, increase transmission, or provide other desirable optical properties. However, an uncoated lens can be suitable for certain applications where such enhancements are not required.
