G314316322 22.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-100mm 450-700nm
This is a Plano-Concave lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a base shape of a circle and a diameter of 22.4 mm. The center thickness of the lens is 1.5 mm, and it has an effective focal length (EFL) of -100 mm, making it a negative lens. The radius of curvature for the concave surface is -52.33 mm.
The lens is made of N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. The wavelength for this lens is 588 nm. It comes with anti-reflection coatings on both the front and back surfaces, specifically Qio Bbar Arb2visnbk7 coatings, designed to reduce surface reflections and increase transmission in the visible spectrum (450-700 nm).
The lens is currently in stock and available for purchase on the Qioptiq Photonics website. For more detailed information and specifications, please refer to the provided weblink.
