LA1274-B N-BK7 Plano-Convex Lens; Dia:30.0 mm; f=40.0 mm ARC 650-1050nm
The LA1274-B is a high-quality Plano-Convex lens from Thorlabs, designed for use in a wide range of optical applications. This lens is fabricated from N-BK7, a popular optical glass known for its excellent optical properties and high damage threshold. The lens has a diameter of 30.0 mm and a focal length of 40.0 mm, making it suitable for use in systems where a long focal length is required.
The lens features an Anti-Reflection coating, designed to reduce surface reflections and increase transmission in the 650-1050nm wavelength range. This coating is applied to both the front and back surfaces of the lens, ensuring optimal performance in both transmission and reflection.
The geometry of the lens is designed for ease of use and integration into optical systems. The lens has a thickness of 2.5 mm at the edge and 9 mm at the center, providing a robust and stable platform for optical systems. The lens also features a radius of curvature of 20.6 mm on the curved surface, and a back focal length of 34 mm.
