LB1917 N-BK7 Bi-Convex Lens; Dia:2 in; f=300.0 mm Uncoated

The LB1917 N-BK7 Bi-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading global manufacturer of photonics equipment. This lens, with a diameter of 2 inches and a focal length of 300.0 mm, is designed for use in a wide range of applications that require precise optical manipulation.

The lens is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is characterized by a high refractive index and low dispersion, making it ideal for use in applications that require high-precision focusing and minimal chromatic aberration. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, uncoated lenses can be advantageous in certain applications where low reflectivity is desired.

The lens geometry is spherical, with both surfaces curved outwards. This bi-convex design provides a large field of view and low spherical aberration, making it suitable for use in imaging systems, beam shaping, and other applications that require high-quality optical transmission. The lens has a central thickness of 5.1 mm and an edge thickness of 3 mm, providing robustness and durability.

The lens is available for purchase through the Thorlabs website, and the provided weblink indicates that it is currently in stock. This information, along with the detailed specifications provided, should help users in their selection process for optical components with similar properties.
