G311384329 12.7 mm Dia. N-BK7 Double-Convex Lens; EFL=50mm 1064nm

This is a G311384329 12.7 mm diameter N-BK7 double-convex lens, specifically designed for use with a center wavelength of 587.6 nm and an effective focal length (EFL) of 50 mm. The lens is sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics.

The lens is spherical in shape, with a base shape of a circle. It features a first radius (r1) of 51.08 mm and a second radius (r2) of -51.08 mm, indicating its double-convex design. The lens has a thickness of 2.2 mm at the edge and 3 mm at the center, providing a robust structure for various applications.

The lens is made from N-BK7, a popular glass type in the optical industry known for its excellent optical properties. This material is particularly suitable for use in the visible and near-infrared regions of the spectrum.

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, making it ideal for use in high-power laser applications.

The lens is currently in stock and available for purchase through the Qioptiq Photonics website. For more information, please refer to the provided weblink.
