LB1471 N-BK7 Bi-Convex Lens; Dia:1 in; f=50.0 mm Uncoated

The LB1471 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 1 inch and a focal length of 50.0 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. This material, also known as BK7, is a borosilicate crown glass with a high refractive index and low dispersion, making it an ideal choice for many optical applications. The N-BK7 designation indicates that this particular lens is made from Schott glass, a renowned manufacturer of high-quality optical glass.

The lens features a bi-convex geometry, meaning it has two convex surfaces. This shape is often used to collimate or focus light, making it a versatile choice for many applications. The lens has a center thickness of 5.2 mm and an edge thickness of 2 mm, providing robustness and durability.

The LB1471 lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. While this may result in higher reflective losses, it also means the lens is less susceptible to damage from environmental factors or handling.
