G314002329 8 mm Dia. N-BK7 Plano-Concave Lens; EFL=-8mm 1064nm
This is a Plano-Concave lens with a diameter of 8 mm, designed for use in optical systems that require a negative focal length. The lens is made from N-BK7, a popular glass type from Schott, known for its excellent optical properties and versatility. The lens has a center thickness of 1 mm and an effective focal length (EFL) of -8 mm, making it suitable for applications that require a concentrated light beam.
The lens's curvature is defined by a radius of -4.134 mm on the concave side. The inner and outer radii are both zero, indicating a uniform curvature across the lens's surface. This lens is unmounted, providing flexibility for integration into various optical 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 reduce surface reflections and increase transmission at a wavelength of 1064 nm, which is commonly used in laser applications.
This lens is available from Qioptiq Photonics, a leading vendor in the field of precision optics. According to the vendor's website, the lens is currently in stock, ensuring quick delivery for your optical project needs.
