The BICV508 is a high-precision double-concave lens, 50 mm in diameter, and featuring an effective focal length (EFL) of -600 mm. This lens is sourced from WTS Photonics, a reputable vendor known for their quality optical elements. The lens is uncoated, offering a cost-effective solution for applications where coating is not a necessity.
The lens's geometry is characterized by its base shape, which is circular, and its double-concave design. The thickness at the edge of the lens is 4 mm, while the center thickness is 3 mm. The back focal length (BFL) is 598.7 mm, and the radii of curvature for the first and second surfaces are -621.28 mm and 621.28 mm, respectively. The lens does not have an inner or outer radius.
The lens is made of n-BK7 Schott, a popular optical material known for its excellent optical properties. It is designed to operate at a wavelength of 546.1 nm. The lens's shape is spherical, a common choice for its ease of manufacturing and good optical performance.
