G311321322 25.4 mm Dia. N-BK7 Double-Convex Lens; EFL=30mm 450-700nm
Discover the G311321322, a 25.4 mm diameter Double-Convex Lens, from the esteemed optical components manufacturer, Qioptiq Photonics. This lens, designed for use within the wavelength range of 450-700nm, features an effective focal length (EFL) of 30mm, making it suitable for a wide range of applications.
The lens is crafted from N-BK7, a high-quality glass commonly used in optical systems due to its excellent homogeneity, low optical dispersion, and exceptional transparency within the visible and near-infrared spectral regions. The N-BK7 material ensures high-quality imaging and minimal chromatic aberration.
The G311321322 boasts a base shape of a circle, with a thickness of 1.4mm at the edge and 7mm at the center. The lens's geometry is designed to provide a superior optical performance, with a radius of curvature of 30.069mm for both the front and rear surfaces.
This lens features a broadband anti-reflection coating, denoted as 'qio bbar arb2visnbk7', on both the front and back surfaces. This coating is specifically designed to reduce surface reflections and increase transmission within the visible spectrum, further enhancing the lens's performance.
