BICV-FS23 38 mm Dia. x -350 mm FL; Uncoated; Double-Concave Lens

The BICV-FS23 is a high-precision double-concave lens, sourced from WTS Photonics, with a diameter of 38 mm and a focal length of -350 mm. This lens is designed for use in applications that require a concave-concave spherical lens with a circular base shape.

The lens features a center thickness of 3 mm and an edge thickness of 4.13 mm, providing a robust and durable structure. The inner and outer radii are both 0, indicating a symmetrical design. The effective focal length (EFL) is -350 mm, and the back focal length (BFL) is 351.03 mm, which should be taken into consideration when integrating this lens into an optical system.

The lens is made from fused silica (mal-1965), a material known for its excellent optical properties, including high transparency and resistance to thermal shock. The wavelength of 546.1 nm suggests this lens is suitable for use in a wide range of applications, from general-purpose to more specific use cases.

Notably, this lens is uncoated. While uncoated lenses can be more cost-effective, they may be more susceptible to surface reflections and could benefit from additional anti-reflective coatings in high-precision applications.
