G063033322 18 mm Dia. N-BK7 Mounted Double-Convex Lens; EFL=16mm 450-700nm
This is the G063033322 model from Qioptiq Photonics, a high-quality 18 mm diameter N-BK7 mounted double-convex lens designed for use in the visible light spectrum, specifically between 450 and 700 nanometers. The lens is characterized by its symmetric convex-convex geometry, making it suitable for a wide range of optical applications.
The lens has an effective focal length (EFL) of 16mm, which is the distance from the lens's center to the focal point where light rays converge. This EFL value, combined with the lens's 18mm diameter, contributes to a compact and efficient optical system.
The lens is made from N-BK7, a popular optical glass from Schott, known for its excellent optical properties and high transmittance in the visible spectrum. The lens's geometry includes an edge thickness of 1.1mm and a center thickness of 7mm, providing robustness and stability.
The lens features broadband anti-reflection coatings on both the front and back surfaces. These coatings, identified as 'qio bbar arb2visnbk7', are designed to minimize surface reflections and increase light transmission, thereby enhancing the overall performance of the lens.
