This is a G311308329 double-convex lens, sourced from the renowned optical components manufacturer, Qioptiq Photonics. The lens boasts a 22.4 mm diameter and a center thickness of 7 mm, with an edge thickness of 1.6 mm, providing a robust and compact design.
The lens is made of N-BK7, a high-quality borosilicate glass, known for its excellent optical properties, including low autofluorescence and high transmittance across a wide spectrum. This makes the lens suitable for various applications, particularly in the visible and near-infrared regions.
The lens has an effective focal length (EFL) of 25 mm, which is the distance from the lens's center to the focal point where light rays converge. This EFL, combined with the lens's double-convex shape, provides a high refractive power, making it ideal for imaging and beam shaping applications.
The lens features a broadband anti-reflection coating on both the front and back surfaces, specifically designed for use with YAG (Yttrium Aluminum Garnet) lasers at a wavelength of 1064 nm. This coating reduces surface reflections, enhancing the lens's transmission efficiency and improving overall system performance.
