LB1391-C N-BK7 Bi-Convex Lens; Dia:1 in; f=400.0 mm ARC 1050-1700nm

The LB1391-C is a high-quality bi-convex lens, designed and manufactured by Thorlabs, a leading global supplier of photonics equipment. This lens is crafted from N-BK7, a type of borosilicate glass known for its excellent optical properties, making it an ideal choice for a wide range of applications.

The lens boasts a diameter of 1 inch, providing a substantial surface area for light transmission. It features a double-convex design, with both surfaces curved outwards, which aids in focusing and collimating light beams. The lens has a focal length of 400.0 mm, determined by the distance from the center of the lens to the point where the light rays converge or diverge.

The LB1391-C is coated with a broadband anti-reflection coating, specifically designed for the 1050-1700nm wavelength range. This coating reduces surface reflections, enhancing the lens's transmission efficiency and overall performance. The lens's geometry includes a thickness of 2 mm at the edge and 3.1 mm at the center, providing structural integrity and resistance to deformation.

This lens is available for immediate purchase and shipping, as indicated by its "in stock" status on the vendor's website. With its superior optical performance, robust design, and broadband anti-reflection coating, the LB1391-C is an excellent choice for various applications in the fields of optics, photonics, and laser technology.
