BICV210 25.4 mm Dia. x -200 mm FL; Uncoated; Double-Concave Lens

The BICV210 is a high-precision double-concave lens, 25.4 mm in diameter, and featuring a focal length of -200 mm. This lens is sourced from WTS Photonics, a reputable vendor known for their quality optical elements. The lens is uncoated, which means it does not have any additional layers to protect or enhance its optical properties.

The lens is designed with a base shape of a circle and has a spherical geometry. The thickness at the edge of the lens is 2.78 mm, while the thickness at the center is 2 mm. The effective focal length (EFL) is -200 mm, and the radii of curvature for the first and second surfaces are -207 mm and 207 mm, respectively. The back focal length (BFL) is 199.07 mm.

The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and high transparency in the visible spectrum. The lens is designed to operate at a wavelength of 546.1 nm.

This lens is ideal for applications that require a strong converging or diverging lens, such as beam shaping, image reduction or expansion, and laser applications. Its high-quality construction and precise specifications make it a reliable choice for various optical systems.
