49-510 50mm Dia. x 150mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
This is a 50mm diameter by 150mm focal length double-convex lens, specifically designed for use in the near-infrared spectrum. The lens is sourced from Edmund Optics and is currently in stock.
The lens is made from n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties. It features a standard curve coating on both the front and back surfaces, specifically Edmund Optics' NIR I coating, which is optimized for the 600-1050nm range. This coating enhances the lens's performance in the near-infrared spectrum, making it ideal for a variety of applications in this range.
The lens's geometry is characterized by a 4.9mm edge thickness and a 9mm center thickness. The front and back radii are 153.49mm and -153.49mm respectively, resulting in a back focal length of 147mm. The lens's inner and outer radii are both 0, indicating a uniform curvature.
