G063025322 22.4 mm Dia. N-BK7 Mounted Double-Convex Lens; EFL=60mm 450-700nm

This is a G063025322 model lens from Qioptiq Photonics, a renowned provider of precision optics. The lens, which has a base shape of a circle, is a symmetric convex-convex spherical lens, specifically designed for use in the optical industry.

The lens has a diameter of 22.4 mm and a thickness at the edge of 2 mm, while the center thickness is 4 mm. The effective focal length (EFL) of this lens is 60 mm, making it suitable for a wide range of applications. The lens is designed to work optimally with light in the wavelength range of 450-700 nm, which covers the visible light spectrum.

The lens is made from N-BK7, a popular type of borosilicate glass known for its excellent optical properties. This material is often used in high-performance optical systems due to its low coefficient of thermal expansion and its high transmittance in the visible and near-infrared regions.

The lens features a broadband anti-reflection coating on both the front and back surfaces. This coating, identified as 'qio bbar arb2visnbk7', is designed to reduce surface reflections and increase the amount of light transmitted through the lens. This makes the lens ideal for use in high-precision optical systems where maximum light transmission is required.
