G313337331 25.4 mm Dia. N-BK7 Double-Concave Lens; EFL=-50mm
This is a G313337331 double-concave lens, featuring a diameter of 25.4 mm and a center thickness of 1.5 mm. The lens is made of N-BK7, a popular glass type in the optical industry known for its excellent optical properties. The effective focal length (EFL) of this lens is -50mm, making it a negative or diverging lens, which spreads out light rays and causes them to diverge.
The lens has two radii of curvature, with the first radius (R1) being -52.33mm and the second radius (R2) being 52.33mm. This double-concave design, where both surfaces of the lens are concave, results in a highly dispersive lens, ideal for applications requiring significant light bending and dispersion.
The lens is coated with Qio AL Ralvis AOI 45 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it suitable for use in various applications, including imaging systems, beam shaping, and laser applications.
The lens is sourced from Qioptiq Photonics, a renowned vendor in the optical industry, ensuring high quality and reliability. The web link provided leads to the product page on their official website, where you can find more information and purchase this lens.
