G314324525 25.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-500mm 725-1050nm
This is a Plano-Concave lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a diameter of 25.4 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, causing them to diverge from a single point.
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 588nm. It comes with a front and back coating of qio bbar arb2nirnbk7, which enhances its durability and performance in the 725-1050nm spectral range.
The lens is unmounted, providing flexibility for users to mount it according to their specific requirements. The inner and outer radii of the lens are 0, indicating a plano surface on one side and a concave surface on the other.
