G052311322 12.7 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-500mm 450-700nm
This is a Plano-Concave lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a diameter of 12.7 mm and a center thickness of 1.5 mm. The effective focal length (EFL) of this lens is -500mm, making it a negative or diverging lens. This means that it spreads out light rays that enter it, causing them to diverge.
The lens is made of N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. This specific lens is coated with qio bbar arb2visnbk7 on both the front and back surfaces, which is a broadband anti-reflection coating designed for use in the visible spectrum (450-700nm). This coating reduces reflection and increases transmission, enhancing the performance of the lens.
The lens is mounted, making it ready for immediate use in optical systems. The curvature of the lens is defined by a radius of -260.39mm on the concave surface. The lens has no inner or outer radius, indicating that it is a simple plano-concave lens.
