G311321329 25.4 mm Dia. N-BK7 Double-Convex Lens; EFL=30mm 1064nm
This is a G311321329 double-convex lens, sourced from Qioptiq Photonics, featuring a 25.4 mm diameter and a design optimized for a wavelength of 587.6 nm. The lens is made of N-BK7, a popular borosilicate crown glass known for its excellent optical properties, making it suitable for various applications.
The lens has an effective focal length (EFL) of 30 mm, providing a moderate level of magnification. Its double-convex geometry, with radii of curvature of 30.069 mm on both sides, contributes to a high refractive power, focusing light efficiently. The lens's edge thickness is 1.4 mm, while the center thickness is 7 mm, ensuring structural rigidity and minimizing optical aberrations.
The lens features Qioptiq's high-performance (HP) anti-reflection (AR) coating, specifically designed for N-BAR and ARHS-YAG wavelengths. This coating reduces surface reflections, enhancing transmission and improving overall system performance.
