LB1630-C N-BK7 Bi-Convex Lens; Dia:2 in; f=100.0 mm ARC 1050-1700nm
The LB1630-C is a high-quality bi-convex lens from Thorlabs, designed for use in a wide range of optical applications. This lens is fabricated from N-BK7 Schott glass, a popular material known for its excellent optical properties and versatility.
The lens features a diameter of 2 inches (50.8 mm) and a focal length of 100.0 mm, making it suitable for applications that require a longer focal length. The lens has a double-convex geometry, with radii of curvature of 101.4 mm for the first surface and -101.4 mm for the second surface. This geometry provides a high degree of focusing power and a large numerical aperture.
The LB1630-C is coated with Thorlabs' Broadband Anti-Reflection Coating (BBAR), which is designed to reduce surface reflections and increase transmission across the 1050-1700 nm wavelength range. This coating ensures optimal performance in near-infrared applications.
The lens has a central thickness of 2.3 mm and an edge thickness of 3 mm, providing excellent mechanical stability and resistance to damage. The lens is also available in stock, as indicated by the "weblink status" in the item data.
