BICV509 50 mm Dia. x -800 mm FL; Uncoated; Double-Concave Lens
The BICV509 is a high-precision double-concave lens, 50 mm in diameter, and featuring an effective focal length (EFL) of -800 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 first radius of curvature (R1) is -828.64 mm, while the second radius (R2) is 828.64 mm, reflecting the double-concave nature of the lens. The thickness at the edge of the lens is 3.8 mm, and at the center, it is 3 mm. The back focal length (BFL) is 798.7 mm, and the lens has no inner or outer radius.
The lens is made of n-BK7 Schott, a popular material in the optical industry due to its excellent optical properties. The lens is designed to operate at a wavelength of 546.1 nm. The shape of the lens is spherical, a common choice for its ease of manufacturing and good optical performance.
