LA1908-C N-BK7 Plano-Convex Lens; Dia:1 in; f=500.0 mm ARC 1050-1700nm
The LA1908-C is a Plano-Convex lens, a type of spherical lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens is designed with a circular base shape and features a diameter of 1 inch, making it suitable for a wide range of optical applications.
The lens has a center thickness of 2.3 mm and an edge thickness of 2 mm, providing a robust structure while maintaining a low profile. The effective focal length (EFL) of this lens is 500 mm, which is a common choice for many optical systems due to its versatility.
The LA1908-C is made from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. This lens is designed to work within the wavelength range of 1050-1700 nm, making it suitable for near-infrared applications.
The lens features a broadband anti-reflection coating, denoted as "tho c bbar" on both the front and back surfaces. This coating is designed to reduce surface reflections and increase transmission, thereby enhancing the overall performance of the lens.
