LA1708-B N-BK7 Plano-Convex Lens; Dia:1 in; f=200.0 mm ARC 650-1050nm

The LA1708-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 borosilicate glass known for its excellent optical properties, making it an ideal choice for applications that require high-performance imaging or light transmission.

The lens has a diameter of 1 inch (25.4 mm) and a focal length of 200 mm, providing a large working distance and a wide field of view. The plano-convex design ensures a flat focal plane, making it suitable for use in microscopy, beam shaping, and other applications where a flat field is required.

The LA1708-B is coated with Thorlabs' Broadband AR Coating (BBAR), which is designed to reduce surface reflections and increase transmission across the 650-1050 nm spectral range. This coating enhances the lens's performance in near-infrared applications, such as bioimaging, spectroscopy, and fiber optics.

The lens has a thickness of 2 mm at the edge and 2.8 mm at the center, providing robustness and durability. The geometry of the lens is designed to minimize spherical aberration, ensuring superior image quality and light transmission.
