G314324400 25.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-500mm
The G314324400 is a plano-concave lens with a diameter of 25.4 mm, sourced from Qioptiq Photonics. This lens is made of N-BK7, a popular glass type known for its excellent optical properties, including a high Abbe number and low dispersion. The lens's concave shape, characterized by a negative focal length of -500mm, is designed to diverge light passing through it.
The lens's geometry includes a center thickness of 1.5 mm and an inner radius of 0 mm, with no specified outer radius. The coating on both the front and back surfaces is Qio Silver RAGV 45, which is likely a broadband anti-reflection coating designed to reduce surface reflections and improve transmission.
This lens is suitable for use in a variety of applications, including imaging systems, beam shaping, and laser applications. However, due to its negative focal length, it is not suitable for use as a focusing element in imaging systems. It is currently in stock and available for purchase on the Qioptiq Photonics website.
