G314332329 12.7 mm Dia. N-BK7 Plano-Concave Lens; EFL=-50mm 1064nm
This is a Plano-Concave lens with a diameter of 12.7 mm, sourced from the renowned optical components manufacturer, Qioptiq Photonics. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility.
The lens features a negative focal length (EFL) of -50mm, making it suitable for applications that require light convergence. The concave shape of the lens allows it to diverge light, making it ideal for use in beam expanders, laser systems, and other applications where light needs to be spread out.
The lens has a center thickness of 1.5 mm, providing a good balance between durability and light transmission. The geometry of the lens is spherical, which is a common shape in optical lenses due to its ease of manufacturing and excellent optical performance.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This anti-reflection coating reduces unwanted reflections and increases light transmission, making the lens more efficient in its function. The coating is specifically designed for use with a wavelength of 588nm, ensuring optimal performance in this spectrum.
