LB1247-C N-BK7 Bi-Convex Lens; Dia:2 in; f=750.0 mm ARC 1050-1700nm

The LB1247-C is a high-quality bi-convex lens, designed and manufactured by Thorlabs, a leading global supplier of photonics equipment. This lens, with a diameter of 2 inches, is constructed from N-BK7, a popular glass type known for its excellent optical properties, including low auto-fluorescence and high damage threshold.

The lens features a focal length of 750.0 mm, making it suitable for applications that require a long focal length. The bi-convex design, with radii of curvature of 772 mm for both the front and back surfaces, ensures a high-quality image with minimal distortion. The lens has a center thickness of 6.2 mm and an edge thickness of 3 mm, providing robustness and durability.

The LB1247-C is coated with Thorlabs' proprietary anti-reflection coating, which is designed to operate over a broad spectrum, from 1050 nm to 1700 nm. This coating reduces surface reflections, improving transmission and enhancing the overall performance of the lens.

This lens is currently in stock, according to the vendor's website, and is available for immediate shipping. With its superior optical performance, robust design, and broad spectral range, the LB1247-C is an excellent choice for a wide range of optical applications.
