G313206000 22.4 mm Dia. N-BK7 Double-Concave Lens; EFL=-30mm Uncoated

The G313206000 is a high-quality double-concave lens from Qioptiq Photonics, featuring a 22.4 mm diameter and a center thickness of 1.5 mm. This lens is made of N-BK7, a popular glass type known for its excellent optical properties, including a high Abbe number and low dispersion. The lens's concave-concave base shape, defined by radii of -31.396 mm and 31.396 mm, contributes to a negative focal length of -30 mm, making it suitable for various applications requiring converging light beams.

The lens's uncoated surface ensures high light transmission while potentially introducing chromatic aberrations due to the lack of anti-reflective coatings. The lens's geometry is designed for use in the visible spectrum, specifically at a wavelength of 588 nm. With its spherical shape and precise dimensions, this lens is an excellent choice for researchers and engineers seeking a reliable, high-performance optical component.
