G313375322 12.7 mm Dia. N-BK7 Double-Concave Lens; EFL=-100mm 450-700nm
This is a G313375322 12.7 mm diameter N-BK7 double-concave lens, specifically designed for use in the visible light spectrum, with a wavelength of 588nm. The lens is sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics.
The lens is of the spherical type, featuring a base shape that is circular. It has a center thickness of 1.5mm and an effective focal length (EFL) of -100mm, making it a powerful tool for focusing or diverging light beams. The first radius of curvature (R1) is -104.41mm, while the second radius (R2) is 104.41mm, indicating a symmetric concave-concave design.
The lens is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. This material is particularly suitable for use in the visible light spectrum, as demonstrated by the lens's specified wavelength range of 450-700nm.
The lens features broadband anti-reflection coatings on both the front and back surfaces. These coatings, identified as 'qio bbar arb2visnbk7', are designed to reduce surface reflections and increase transmission, thereby enhancing the lens's performance in a variety of applications.
