67-620 10mm Dia. x 50mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
This is a 10mm diameter, double-convex lens with a focal length of 50mm, specifically designed for use in the near-infrared (NIR) spectrum. The lens is sourced from Edmund Optics, a leading provider of optical components, and is currently in stock.
The lens is made from N-BK7 Schott glass, a popular material for optical lenses due to its excellent optical properties and wide transparency range. The lens features a standard curve coating on both the front and back surfaces, specifically the EDM NIR-II coating, which is designed to enhance performance in the NIR II range of 750-1550nm.
The lens has a center thickness of 2.5mm and an edge thickness of 2.01mm. The front and back radii of curvature are 51.25mm and -51.25mm respectively, resulting in a back focal length of 49.17mm. The lens has no inner or outer radius, indicating a uniform thickness.
This lens is a spherical lens, meaning it has a spherical surface. The double-convex design, where both surfaces are convex, provides a wide field of view and low distortion. This makes it suitable for a variety of applications, including imaging, spectroscopy, and beam shaping.
