BICV-FS24 38 mm Dia. x -500 mm FL; Uncoated; Double-Concave Lens

The BICV-FS24 is a high-precision double-concave lens, 38 mm in diameter, with a focal length of -500 mm, sourced from WTS Photonics. This uncoated lens boasts a unique double-concave shape, making it an ideal choice for various applications requiring precise optical manipulation.

The lens's geometry is meticulously designed, featuring an edge thickness of 3.78 mm and a center thickness of 3 mm. The radii of curvature for the first and second surfaces are -460.55 mm and 460.55 mm, respectively, resulting in a back focal length of 501.02 mm. The lens's inner and outer radii are both zero, indicating a uniform curvature across the lens surface.

The lens is crafted from fused silica (mal-1965), a material known for its excellent optical properties, including high transparency and resistance to thermal shock. The wavelength of operation is 546.1 nm, making it suitable for a wide range of applications in the visible spectrum.

Notably, the lens is uncoated, offering bare substrate performance. While coatings can enhance certain optical properties, such as reducing surface reflections or increasing damage threshold, this lens provides a cost-effective solution for applications where such enhancements are not required.
