This is a plano-convex lens, type 47-387-INK, sourced from Edmund Optics, a renowned vendor in the optical industry. The lens boasts a diameter of 25.0mm and a focal length of 500.0mm, making it suitable for a wide range of applications.
The lens is constructed from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It features a spherical shape, with a front radius of curvature of 258.4mm and a back focal length of 497.89mm. The lens has an edge thickness of 2.9mm and a center thickness of 3.2mm, providing robustness and durability.
The lens is coated with edm visnir0sp2002000 on both the front and back surfaces. This coating enhances its performance in the visible (VIS) and near-infrared (NIR) spectrum, specifically between 400-1000nm. This makes the lens ideal for applications that require broadband transmission, such as spectroscopy, biomedical imaging, and machine vision.
