G311320329 22.4 mm Dia. N-BK7 Double-Convex Lens; EFL=200mm 1064nm

This is a G311320329 lens, a high-quality optical component sourced from Qioptiq Photonics. It is a double-convex lens, characterized by its spherical shape and symmetrical convex-convex design. The lens has a diameter of 22.4 mm and a thickness of 2.4 mm at the edge, with a center thickness of 3 mm.

The lens is made of N-BK7, a popular optical glass type known for its excellent optical properties. This material is particularly suitable for use in the visible and near-infrared spectral regions. The lens has an effective focal length (EFL) of 200 mm, making it a medium to long-range focal length lens.

The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, particularly at the 1064 nm wavelength.

The lens is unmounted, providing users with the flexibility to integrate it into their optical systems according to their specific requirements. It is currently in stock and available for purchase through the Qioptiq Photonics website.
