G311341000 40 mm Dia. N-BK7 Double-Convex Lens; EFL=65mm 450-700nm
This is the G311341000, a high-quality double-convex lens from Qioptiq Photonics. The lens, which has a base shape of a circle, is designed for use in the visible light spectrum, specifically optimized for the wavelength of 587.6 nm.
The lens has a diameter of 40 mm and a thickness at the edge of 1.9 mm. The center thickness is 8 mm, providing a robust structure for various applications. The effective focal length (EFL) of this lens is 65 mm, making it suitable for use in systems that require a longer focal length.
The lens is made from N-BK7, a popular glass type known for its excellent optical properties. This material is Schott's borosilicate glass 3.3, which is known for its low coefficient of thermal expansion and high transmittance in the visible and near-infrared regions.
The G311341000 is coated with qio bbar arb2visnbk7 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission in the visible light spectrum.
The lens's geometry is spherical, with radii of curvature of 67.317 mm for both the front and back surfaces. This symmetrical design helps to minimize spherical aberration, ensuring high-quality imaging.
