G312403322 31.5 mm Dia. N-BK7 Plano-Convex Lens; EFL=80mm 450-700nm

The G312403322 is a Plano-Convex lens with a diameter of 31.5 mm, sourced from the renowned optical components manufacturer, Qioptiq Photonics. This lens is designed for use within the wavelength range of 450-700nm, making it suitable for a wide array of optical applications.

The lens is made from N-BK7, a popular glass type known for its excellent optical properties. The Plano-Convex geometry, where one side is flat and the other is curved, is a common choice in optical systems due to its ease of use and versatility. The curvature of this particular lens is defined by a radius of 41.57mm.

The lens has an effective focal length (EFL) of 80mm, a critical specification that determines the lens's focusing power. The edge thickness of the lens is 1.9mm, while the center thickness is 5mm, providing a good balance between optical performance and mechanical robustness.

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 transmission, thereby enhancing the overall performance of the lens in the specified wavelength range.
