G052204322 12.5 mm Dia. N-BK7 Mounted Double-Convex Lens; EFL=12.5mm 450-700nm
This is a G052204322 12.5 mm diameter N-BK7 mounted double-convex lens, specifically designed for use in the visible light spectrum, between 450 and 700 nanometers. The lens is sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics.
The lens is of the spherical type, with a base shape of a circle. It features a double-convex geometry, meaning it has two convex surfaces. The first surface (R1) has a radius of curvature of 11.971 mm, while the second surface (R2) has a radius of curvature that is the negative of the first, at -11.971 mm. This symmetric design ensures a high degree of optical quality.
The lens has an effective focal length (EFL) of 12.5 mm, which is also its diameter. The edge thickness of the lens is 1 mm, while the center thickness is 4.5 mm. The lens is made from N-BK7, a popular type of borosilicate glass known for its excellent optical properties.
The lens is coated with qio bbar arb2visnbk7 on both the front and back surfaces. This coating is designed to enhance the lens's performance in the visible light spectrum, reducing reflection and increasing transmission.
The lens is mounted, making it ready for immediate use in optical systems. The item data does not provide specific details about the mount, so users should consult the vendor for more information.
