BICV-FS20 38 mm Dia. x -100 mm FL; Uncoated; Double-Concave Lens

The BICV-FS20 is a high-precision double-concave lens, 38 mm in diameter, and featuring a focal length of -100 mm. This lens is sourced from WTS Photonics, a reputable vendor in the optical industry. The lens is made of fused silica (mal-1965), a material known for its excellent optical properties, making it suitable for various applications.

The lens's geometry is characterized by its double-concave shape, with radii of curvature of -92.49 mm and 92.49 mm for the first and second surfaces, respectively. This shape results in a back focal length of 101.03 mm. The lens's edge thickness is 6.95 mm, while the center thickness is 3 mm, providing robustness and durability.

The lens is uncoated, which means it does not have any anti-reflective or other coatings. This may be suitable for applications where such coatings are not required or desirable. However, users should be aware that uncoated lenses may have higher reflectivity and may be more susceptible to environmental conditions.

The lens is designed for use at a wavelength of 546.1 nm. It is spherical in shape, a common and versatile geometry in optical systems. The provided data suggests that this lens is in stock and ready for immediate use or integration into optical systems.
