This is a G052102322 3 mm Dia. N-BK7 Mounted Plano-Convex Lens, specifically designed for use in the visible light spectrum, spanning from 450 to 700 nanometers. The lens is sourced from the reputable vendor, Qioptiq Photonics.
The lens is a spherical type, with a base shape of a circle. It features a plano-convex geometry, which means one side is flat (plano), and the other side is curved (convex). The diameter of the lens is 3 millimeters, and it has a center thickness of 1.5 millimeters and an edge thickness of 0.34 millimeters. The effective focal length (EFL) of the lens is 3 millimeters.
The lens is made of N-BK7, a type of glass manufactured by Schott AG, which is known for its excellent optical properties. This material is often used in high-precision optical systems due to its low optical dispersion and high Abbe number.
The lens is coated with qio bbar arb2visnbk7 on both the front and back surfaces. This coating is designed to enhance the lens's performance in the visible light spectrum, reducing reflection and increasing transmission.
The item data also indicates a specific shape for the lens, which is spherical. This means that the curvature of the lens is uniform across its surface, following the shape of a sphere.
