G314334329 12.7 mm Dia. N-BK7 Plano-Concave Lens; EFL=-200mm 1064nm
This is a Plano-Concave lens with a diameter of 12.7 mm, sourced from Qioptiq Photonics. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. The lens's design is spherical, with a concave shape on one side and a flat surface on the other.
The lens has an effective focal length (EFL) of -200mm, making it a negative lens. This means that it diverges light, which can be useful in various applications such as beam expansion or collimation. The lens's thickness at the center is 1.5 mm, and it has an inner radius of 0 mm and an outer radius of 0 mm.
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 1064nm wavelength. The lens is available for purchase from the Qioptiq Photonics website, where it is currently in stock.
