BICV105 12.7 mm Dia. x -40 mm FL; Uncoated; Double-Concave Lens

The BICV105 is a high-precision double-concave lens, 12.7 mm in diameter, and featuring a focal length of -40 mm. Manufactured by WTS Photonics, this lens is designed for use in a variety of optical applications, offering excellent performance and reliability.

The lens is constructed from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material makes the lens suitable for use across a wide range of wavelengths, with a specified center wavelength of 546.1 nm.

The geometry of the lens is characterized by its concave-concave shape, with a base shape of circular. The edge thickness measures 2.99 mm, while the center thickness is 2 mm. The effective focal length (EFL) is -40 mm, and the back focal length (BFL) is 39.04 mm. The radii of curvature for the first and second surfaces are -41.02 mm and 41.02 mm, respectively.

Notably, this lens is uncoated, which may be suitable for certain applications where anti-reflective coatings are not required or desirable. However, users should be aware that uncoated lenses can suffer from increased reflection, which may impact overall system performance.
