G063070000 22.4 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-40mm Uncoated
This is a 22.4 mm diameter Plano-Concave lens, manufactured by Qioptiq Photonics, featuring a negative focal length (EFL) of -40mm. The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and high transmittance in the visible spectrum.
The lens geometry includes a center thickness of 1.5mm, with the concave surface having a radius of curvature of -20.833mm. The lens is uncoated, which means it does not have any anti-reflective or other surface coatings. This can result in higher reflective losses, but it also means that the lens is more cost-effective and suitable for applications where such losses are not critical.
The lens is mounted, which means it is ready to be integrated into an optical system without the need for additional mounting or centering. This can save time and effort in the assembly process.
