LB1106 N-BK7 Bi-Convex Lens; Dia:2 in; f=125.0 mm Uncoated

The LB1106 N-BK7 Bi-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of precision photonics. This lens, with a diameter of 2 inches and a focal length of 125.0 mm, is designed for use in a wide range of optical systems, including imaging, beam shaping, and laser applications.

The lens is made from N-BK7, a popular glass type known for its excellent optical properties. It is a spherical lens, featuring two convex surfaces with radii of curvature of 127.4 mm each. This bi-convex design allows for efficient light transmission and focusing. The lens has an effective focal length (EFL) of 125.0 mm, which is the distance from the lens's center to the focal point when the lens is used in air.

The lens's geometry includes a thickness of 3 mm at the edge and 8.1 mm at the center. The back focal length (BFL), which is the distance from the rear surface of the lens to its focal point, is 122.3 mm. The lens does not have any coating, which means it is uncoated. However, it can be customized with various coatings to enhance its performance in specific applications.

This lens is available for purchase directly from Thorlabs, and the vendor's website indicates that it is currently in stock. The item data also includes a weblink to the product page for easy reference and further details.
