G052403322 12.7 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-50mm 450-700nm

This is a G052403322 model double-concave lens, featuring a 12.7 mm diameter and a center thickness of 1.5 mm. The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and wide transparency range.

The lens has a negative focal length (EFL) of -50mm, making it suitable for use in various applications that require light convergence. It is designed to work within the wavelength range of 450-700nm, which covers the visible light spectrum, making it ideal for use in visible light applications.

The lens 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, thereby improving the overall efficiency and quality of the optical system in which it is used.

The lens's geometry is spherical, with both surfaces curved inward (concave). The radii of curvature for the first and second surfaces are -52.33mm and 52.33mm, respectively. The lens is mounted, indicating that it is ready for immediate use in optical systems.

This lens is available from Qioptiq Photonics, a leading vendor in the field of precision optics. According to the vendor's website, the lens is currently in stock, ensuring quick delivery upon order.
