BICV-FS19 38 mm Dia. x -50 mm FL; Uncoated; Double-Concave Lens
The BICV-FS19 is a high-precision double-concave lens, boasting a diameter of 38 mm and a focal length of -50 mm. Manufactured by WTS Photonics, this lens is sourced from their extensive catalog of optical elements, ensuring quality and reliability.
This lens is designed with a base shape of a circle and features a spherical geometry. The lens's thickness at the edge is 11.12 mm, while its center thickness is a mere 3 mm, providing a sleek and compact design. The effective focal length (EFL) is -50 mm, and the radii of curvature are -46.48 mm for the first surface and 46.48 mm for the second surface. The back focal length (BFL) is 51.02 mm, and both the inner and outer radii are 0 mm.
The lens is made from fused silica (mal-1965), a material known for its excellent optical properties and durability. The wavelength for this lens is 546.1 nm. Notably, this lens does not have any coating, which may affect its performance in certain applications. However, its uncoated state also means it can be easily customized or adapted to specific user needs.
