G312357525 12.7 mm Dia. N-BK7 Plano-Convex Lens; EFL=300mm 725-1050nm
The G312357525 is a Plano-Convex lens with a diameter of 12.7 mm, sourced from the renowned optical components manufacturer, Qioptiq Photonics. This lens is designed for use within the wavelength range of 725-1050nm, making it suitable for a variety of applications within this spectrum.
The lens is made from N-BK7, a popular optical glass known for its excellent optical properties, including a high Abbe number and low dispersion. This makes it an ideal choice for applications that require high image quality and low chromatic aberration.
The lens has an effective focal length (EFL) of 300mm, providing a moderate level of magnification. The plano-convex design, where one side is flat and the other is curved, allows for efficient light collection and focusing. The radius of curvature of the curved surface is 153.99mm.
The lens has a thickness of 2.9mm at the edge and 3mm at the center. This slight asymmetry is a common characteristic of plano-convex lenses and can be accounted for in optical designs.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, enhancing the performance of the lens in its intended application.
