G063070525 22.4 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-40mm 725-1050nm
This is a mounted plano-concave lens, type G063070525, with a diameter of 22.4 mm, sourced from Qioptiq Photonics. The lens is made of N-BK7, a popular material in the optical industry due to its excellent optical properties. The lens's geometry includes a center thickness of 1.5 mm and an effective focal length (EFL) of -40 mm, making it suitable for a variety of applications.
The lens's concave surface has a radius of curvature of -20.833 mm. The lens is uncoated, but it is available with a broadband anti-reflection coating (BBAR) on both the front and back surfaces, specifically designed for use in the 725-1050 nm wavelength range. This coating helps to reduce surface reflections, thereby increasing transmission and improving overall system performance.
The lens is mounted, providing convenience and ease of use. The provided web link leads to the vendor's website, where you can find more information about the lens, including its current availability and pricing.
