This is a 25.4 mm diameter Plano-Concave lens, manufactured by Qioptiq Photonics, a leading provider of precision optics. The lens is made of N-BK7, a popular borosilicate glass known for its excellent optical properties and high damage threshold. The lens features a concave shape with a center thickness of 1.5 mm and an effective focal length (EFL) of -200mm, making it suitable for use in imaging systems where a negative lens is required.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission in the 725-1050nm wavelength range, making it ideal for use in near-infrared (NIR) applications.
The lens is mounted, providing a convenient and ready-to-use solution for your optical system. The item data indicates that this lens is in stock and available for immediate purchase, making it a great option for those needing a high-quality, NIR-optimized Plano-Concave lens quickly.
