G312325322 25.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=200mm 450-700nm

The G312325322 is a 25.4 mm diameter Plano-Convex lens, sourced from the reputable 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 within the visible light spectrum.

The lens is fabricated 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 for many optical systems due to its simplicity and versatility. The lens has a center thickness of 4mm and an edge thickness of 3.2mm, providing a robust structure while maintaining a sleek profile.

The lens's effective focal length (EFL) is 200mm, a characteristic that significantly influences the lens's magnification and field of view. This EFL makes the G312325322 a medium to long-focus lens, ideal for applications requiring a narrow field of view and high magnification.

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 system performance.
