BICV504 50 mm Dia. x -250 mm FL; Uncoated; Double-Concave Lens

The BICV504 is a high-precision double-concave lens, sourced from WTS Photonics, with a diameter of 50 mm and a focal length of -250 mm. This uncoated lens boasts a base shape of a circle and is designed for use with a wavelength of 546.1 nm.

The lens's geometry is characterized by an edge thickness of 5.4 mm and a center thickness of 3 mm. The radii of curvature for the first and second surfaces are -258.22 mm and 258.22 mm, respectively. The back focal length measures 248.2 mm, and both the inner and outer radii are 0 mm.

The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material makes the lens suitable for a wide range of applications, including but not limited to, imaging systems, beam shaping, and laser applications.

Please note that the lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors. However, this does not affect its performance in applications where such coatings are not required.
