G313374331 12.7 mm Dia. N-BK7 Double-Concave Lens; EFL=-50mm
This is a G313374331 12.7 mm Dia. N-BK7 Double-Concave Lens, with a focal length (EFL) of -50mm, sourced from Qioptiq Photonics. The lens is designed for use in the visible light spectrum, specifically at a wavelength of 588nm.
The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and high homogeneity. This material is widely used in various optical applications due to its low dispersion and high Abbe number.
The lens features a double-concave geometry, with a diameter of 12.7mm and a center thickness of 1.5mm. The radii of curvature for the first and second surfaces are -52.33mm and 52.33mm, respectively. The lens does not have an inner or outer radius.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission, enhancing the overall performance of the lens.
The lens is available for purchase from the Qioptiq Photonics website, and as of the time of data collection, it is in stock. The provided weblink leads directly to the product page for easy access and purchase.
