G063061525 22.4 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-50mm 725-1050nm
This is a G063061525 model lens, a high-quality optical component manufactured by Qioptiq Photonics. It is a mounted double-concave lens made of N-BK7 material, a popular choice for its excellent optical properties and versatility. The lens has a diameter of 22.4 mm and a center thickness of 1.5 mm, making it suitable for a wide range of applications.
The lens's effective focal length (EFL) is -50mm, indicating its concave nature. This type of lens is often used to diverge light beams or to reduce the convergence of a lens system. The wavelength of operation is 588nm, which falls within the visible light spectrum.
The lens features a broadband anti-reflection coating on both the front and back surfaces. This coating, identified as 'qio bbar arb2nirnbk7', is designed to minimize reflection losses and enhance transmission across the entire spectral range of 725-1050nm. This makes the lens ideal for use in systems that require high transmission and low loss, such as laser applications, imaging systems, and optical metrology.
