G311323331 25.4 mm Dia. N-BK7 Double-Convex Lens; EFL=80mm
This is a G311323331 model double-convex lens, featuring a 25.4 mm diameter and a 5 mm thickness at the edge, gradually increasing to 7 mm at the center. The effective focal length (EFL) of this lens is 80 mm, making it suitable for a variety of optical applications.
The lens is made of N-BK7, a type of borosilicate glass commonly used in optical systems due to its excellent optical properties. The radii of curvature for this lens are r1 = 81.166 mm and r2 = -81.166 mm, indicating a symmetric convex-convex design. The inner and outer radii are both 0, suggesting a uniform curvature throughout the lens.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This coating is designed to reduce reflection and improve transmission, enhancing the overall performance of the lens. The lens is spherical in shape, a common design for optical elements due to its ease of manufacturing and versatility.
The vendor for this lens is Qioptiq Photonics, a reputable company known for its high-quality optical components. According to the vendor, this lens is currently in stock and available for purchase.
