BICV503 50 mm Dia. x -200 mm FL; Uncoated; Double-Concave Lens
The BICV503 is a high-precision double-concave lens, 50 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, offering a bare, unaltered glass surface that is suitable for applications where coating is not required or preferred.
The lens is designed with a base shape of a circle, and its geometry is characterized by a thickness of 6 mm at the edge and 3 mm at the center. The effective focal length (EFL) is -200 mm, and the radii of curvature are -206.28 mm for the first surface and 206.28 mm for the second surface. The back focal length (BFL) is 198 mm, and both the inner and outer radii are 0 mm.
This lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The lens is designed for a wavelength of 546.1 nm, making it suitable for applications that utilize this wavelength.
