LB1106-C N-BK7 Bi-Convex Lens; Dia:2 in; f=125.0 mm ARC 1050-1700nm

The LB1106-C is a high-quality bi-convex lens from Thorlabs, designed for use in a wide range of optical applications. This lens is fabricated from N-BK7 Schott glass, a popular material known for its excellent optical properties and versatility.

The lens features a diameter of 2 inches (50.8 mm) and a focal length of 125.0 mm, providing a beam divergence that can be precisely controlled. The lens has a double-convex geometry, with radii of curvature of 127.4 mm for both the front and back surfaces. This design allows for efficient light collection and focusing, making it suitable for use in imaging systems, beam shaping, and other applications where high-quality optical performance is required.

The LB1106-C is coated with Thorlabs' Broadband Anti-Reflection Coating (ARC), which is designed to reduce surface reflections and increase transmission across the 1050-1700 nm wavelength range. This coating ensures optimal performance in near-infrared (NIR) applications, such as fiber optics, bio-imaging, and spectroscopy.

In terms of dimensions, the lens has a thickness of 3 mm at the edge and 2.2 mm at the center, providing a robust and compact design. The lens is available for purchase directly from Thorlabs, and the provided weblink offers up-to-date information on product availability and pricing.
