G312009525 7 mm Dia. N-BK7 Plano-Convex Lens; EFL=7mm 725-1050nm

This is a Plano-Convex lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a circular base shape with a diameter of 7 mm and a thickness that varies from 0.8 mm at the edge to 3.5 mm at the center. The effective focal length (EFL) of this lens is 7 mm, making it suitable for applications that require a short focal length.

The lens is made of N-BK7, a popular glass type in the optical industry known for its excellent optical properties. The inner and outer radii of the lens are 0, indicating a plano surface on one side and a curved surface on the other. The curvature of the curved surface is defined by a radius of 3.62 mm.

This lens is designed to operate within the wavelength range of 725-1050 nm, making it suitable for near-infrared applications. The lens comes with a broadband anti-reflection coating, specifically the Qio Bbar Arb2nirnbk7 coating, on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, enhancing the lens's performance in its intended application.

The item data also indicates that this particular lens is in stock and available for purchase, making it a readily available option for users seeking a lens with these specifications.
