BICV207 25.4 mm Dia. x -125 mm FL; Uncoated; Double-Concave Lens

The BICV207 is a high-precision double-concave lens, 25.4 mm in diameter, and featuring a focal length of -125 mm. This lens is sourced from WTS Photonics, a reputable vendor known for their quality optical elements. The lens is uncoated, offering a clear, unaltered view of the light path.

The lens is designed with a base shape of a circle and has a spherical geometry. The thickness at the edge is 3.25 mm, while the center thickness is 2 mm. The effective focal length (EFL) is -125 mm, and the back focal length (BFL) is 123.92 mm. The radii of curvature for the first and second surfaces are -129.12 mm and 129.12 mm, respectively.

This lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The lens is designed to operate at a wavelength of 546.1 nm. The lack of a coating on this lens allows for raw interaction with light, making it suitable for applications where minimal reflection and dispersion are required.
