G063892525 25.4 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-50mm 725-1050nm
This is a high-quality, mounted double-concave lens from Qioptiq Photonics, designed for precision optical applications. The lens has a diameter of 25.4 mm and a center thickness of 1.5 mm, making it suitable for a wide range of optical systems.
The lens features a focal length of -50 mm, which is ideal for applications that require a strong converging or diverging effect. The double-concave design ensures that light rays are effectively refracted, making this lens suitable for use in imaging systems, beam shaping, and other applications where precise light control is required.
The lens is made from N-BK7 glass, a popular material for optical elements due to its excellent optical properties and high damage threshold. The glass is coated with a broadband anti-reflection coating (Qio Bbar ARB2NIRNBK7), which reduces surface reflections and increases transmission across the 725-1050nm wavelength range.
The lens is mounted, providing a convenient and secure way to integrate it into optical systems. The mounting mechanism ensures that the lens remains properly aligned, reducing the need for adjustments during operation.
