G063061329 22.4 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-50mm 1064nm

This is a G063061329 model lens from Qioptiq Photonics, a renowned vendor in the field of precision optics. The lens is a symmetric concave design, featuring a base shape of a circle, and is mounted for convenience.

The lens has a diameter of 22.4 mm and a center thickness of 1.5 mm. The effective focal length (EFL) is -50 mm, indicating that it is a double-concave lens. The first radius of curvature (R1) is -52.33 mm, and the second radius of curvature (R2) is 52.33 mm, which are identical in magnitude but opposite in sign, further confirming the double-concave nature of the lens.

The lens is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. The wavelength for this lens is 588 nm.

The lens comes with a coating on both the front and back surfaces. The front coating is Qio HP Nbar ARHS-YAG, and the back coating is also Qio HP Nbar ARHS-YAG. This coating enhances the lens's performance by reducing reflection and increasing transmission.

The lens's shape is spherical, which is a common shape for optical lenses due to its ease of manufacturing and good optical performance.

The lens is currently in stock and can be purchased from the Qioptiq Photonics website.
