BICV-FS22 38 mm Dia. x -200 mm FL; Uncoated; Double-Concave Lens

The BICV-FS22 is a high-precision double-concave lens, sourced from WTS Photonics, with a diameter of 38 mm and a focal length of -200 mm. This lens is designed for use in applications that require a concave-concave spherical lens with a circular base shape.

The lens's geometry is meticulously crafted, with an edge thickness of 4.96 mm and a center thickness of 3 mm. The effective focal length (EFL) is -200 mm, and the radii of curvature are -184.5 mm for the first surface and 184.5 mm for the second surface. The back focal length (BFL) is 201.02 mm, and both the inner and outer radii are 0 mm, indicating a flat profile.

The lens is made from fused silica (mal-1965), a material known for its high transparency and resistance to thermal shock. It is designed for use at a wavelength of 546.1 nm. The lens does not come with any coating, offering a bare, uncoated surface.
