This is a 10mm diameter, 50mm focal length double-convex lens, specifically designed for use in the near-infrared (NIR) spectrum. The lens is sourced from Edmund Optics and is currently in stock.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and chemical durability. It features a standard curve coating on both the front and back surfaces, specifically the EDM NIR-I coating, which is designed to enhance performance in the 600-1050nm wavelength range.
The lens has a center thickness of 2.5mm and an edge thickness of 2.01mm, providing a robust structure while maintaining a low profile. The front and back radii of the lens are 51.25mm and -51.25mm respectively, indicating a strongly converging lens. The back focal length is 49.17mm, and the effective focal length is 50mm.
This lens is suitable for a wide range of applications, including but not limited to, spectroscopy, machine vision, and other NIR-based imaging systems. Its high-quality construction, combined with its specific NIR coating, makes it an ideal choice for applications that require superior performance in the NIR spectrum.
