This is a G311323329 double-convex lens, featuring a 25.4 mm diameter and a focal length of 80 mm at a wavelength of 1064 nm. The lens is sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics.
The lens is made of N-BK7, a popular glass type known for its excellent optical properties, including a high Abbe number and low dispersion. This makes it suitable for various applications that require high-quality imaging and minimal chromatic aberration.
The lens has a symmetric convex-convex geometry, with a thickness of 5 mm at the edge and 7 mm at the center. The inner and outer radii are 0, indicating a uniform curvature throughout the lens. This shape allows for a wide field of view and a high light-gathering capability.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, particularly at the specified wavelength. It also provides protection against environmental factors, ensuring the longevity and reliability of the lens.
