G314317329 22.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-150mm 1064nm
This is a Plano-Concave lens with a diameter of 22.4 mm, sourced from the renowned optical components manufacturer, Qioptiq Photonics. The lens is made of N-BK7, a popular glass type known for its excellent optical properties, especially in the visible and near-infrared spectral regions.
The lens features a concave shape with a radius of curvature of -78.298 mm, resulting in a negative focal length (EFL) of -150 mm at a wavelength of 1064 nm. This makes it suitable for applications that require light convergence or divergence, such as beam expanding or focusing.
The lens has a center thickness of 1.5 mm, providing a good balance between mechanical strength and optical performance. The lens is unmounted, offering flexibility in integration with other optical components or systems.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This anti-reflection coating is designed to minimize surface reflections and increase transmission, particularly at the YAG laser wavelength of 1064 nm.
The lens is currently in stock and can be purchased directly from the Qioptiq Photonics website. For more information, please refer to the provided weblink.
