G063875322 25.4 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-1000mm 450-700nm

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 negative focal length (EFL) of -1000mm, making it suitable for applications that require light convergence or divergence. The plano-concave design, where one surface is flat and the other is curved, allows for precise control of the light path.

The lens is coated with Qio Bbar Arb2visnbk7 on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission in the 450-700nm spectral range, enhancing the lens's performance in visible light applications.

The lens has a center thickness of 1.5mm and a spherical shape. The inner and outer radii are 0mm, indicating a sharply curved concave surface. The lens is mounted, providing convenience and ease of use in optical systems.
