LA1859 N-BK7 Plano-Convex Lens; Dia:18.0 mm; f=20.0 mm Uncoated

The LA1859 N-BK7 Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical components. This lens, with a diameter of 18.0 mm, is designed to meet the demands of various optical applications.

The lens is spherical in shape, specifically a Plano-Convex lens, which means it has a flat surface on one side and a curved surface on the other. The curvature of the lens is defined by a radius of 10.3 mm, which is the radius of the curvature of the curved surface. The lens's effective focal length (EFL) is 20.0 mm, which is the distance from the lens's center to the focal point when the lens is used in an imaging system.

The lens is made of N-BK7, a type of glass commonly used in optical systems due to its excellent optical properties. The glass has an inner radius of 0 mm and an outer radius of 0 mm, indicating that the lens is uniformly thick. The thickness at the edge of the lens is 1.8 mm, while the thickness at the center is 7.1 mm.

The lens is uncoated, meaning it does not have any anti-reflective or other coatings. This may be suitable for applications where such coatings are not required or desirable.

According to the vendor's website, the lens is in stock, indicating its availability for immediate purchase and use. The website also provides further technical details and specifications for the lens, which can be accessed via the provided web link.
