67-619 10mm Dia. x 40mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
This is a 10mm diameter, 40mm focal length double-convex lens, 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, a high-quality borosilicate glass known for its excellent optical properties. It features a standard NIR-II coating on both the front and back surfaces, designed to enhance transmission and reduce reflection in the NIR range of 750-1550nm.
The lens has a center thickness of 2.5mm and an edge thickness of 1.89mm, providing a robust and durable construction. The front and back radii of curvature are 40.91mm and -40.91mm respectively, resulting in a back focal length of 39.16mm. The lens has a spherical shape, which is ideal for a wide range of optical applications.
