LB1187 N-BK7 Bi-Convex Lens; Dia:0.5 in; f=100.0 mm Uncoated

The LB1187 N-BK7 Bi-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical equipment. This lens, with a diameter of 0.5 inches and a focal length of 100.0 mm, is designed for use in a wide range of optical systems, making it a versatile choice for many applications.

The lens is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is characterized by a high refractive index and low dispersion, making it ideal for use in high-precision optical systems. The lens is uncoated, which means it does not have any additional layers applied to its surface to alter its optical properties.

The geometry of the lens is carefully designed to provide optimal performance. It has a diameter of 12.7 mm, with a thickness of 1.8 mm at the edge and 2.2 mm at the center. The lens's effective focal length (EFL) is 100.0 mm, and its back focal length (BFL) is 99.3 mm. The radii of curvature for the first and second surfaces of the lens are 102.6 mm and -102.6 mm, respectively.

This lens is a spherical lens with a convex-convex shape, meaning both of its surfaces are curved outwards. This shape is often used in optical systems where a high degree of focusing is required. The lens's circular base shape ensures it can be easily integrated into a variety of optical setups.
