G052208322 12.7 mm Dia. N-BK7 Mounted Double-Convex Lens; EFL=50mm 450-700nm

This is a G052208322 lens, a high-quality optical component manufactured by Qioptiq Photonics. It is a mounted double-convex lens, featuring a base shape of a circle, which is typical for this type of lens. The lens has a diameter of 12.7 mm, making it suitable for a wide range of applications where compactness and precision are required.

The lens has a thickness of 2.2 mm at the edge and 3 mm at the center, providing a robust structure while maintaining a sleek profile. The effective focal length (EFL) of this lens is 50 mm, which is a common choice for many optical systems due to its versatility.

The lens is made of N-BK7, a high-grade optical glass from Schott, known for its excellent optical properties and durability. This material is particularly suitable for applications in the visible spectrum, as indicated by the wavelength of 587.6 nm.

The lens features a broadband anti-reflection coating on both the front and back surfaces. This coating, identified as 'qio bbar arb2visnbk7', is specifically designed to reduce surface reflections and increase transmission in the visible spectrum (450-700 nm). The coating ensures optimal performance and minimal loss of light, which is crucial for many optical applications.
