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 -50 mm. The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties.
The lens is designed to operate within the wavelength range of 588 nm. It comes with a front and back coating of qio bbar arb2nirnbk7, which is a broadband anti-reflection coating. This coating helps to reduce surface reflections and increase transmission, making it suitable for use in various optical systems.
The lens is mounted, making it ready for immediate use in optical systems. The web link provided is valid and the lens is in stock, making it readily available for purchase. This lens is a great option for those looking for a high-quality, mounted Plano-Concave lens with a wide wavelength range and broadband anti-reflection coating.
