LA1274-C N-BK7 Plano-Convex Lens; Dia:30.0 mm; f=40.0 mm ARC 1050-1700nm
The LA1274-C 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 glass, a popular material known for its excellent optical properties and versatility. The lens has a diameter of 30.0 mm and a focal length of 40.0 mm, making it suitable for applications that require a long focal length.
The lens geometry includes a thickness of 2.5 mm at the edge and 9 mm at the center, providing a robust structure while maintaining a low profile. The front and back surfaces of the lens are coated with a broadband anti-reflection coating, designed to operate in the 1050-1700 nm range. This coating reduces surface reflections, enhancing the overall transmission of the lens and improving the system's performance.
The lens's spherical shape ensures excellent image quality and low distortion, making it ideal for imaging and beam shaping applications. The lens is currently in stock, as indicated by its valid weblink status, making it readily available for immediate use.
