G063872322 25.4 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-100mm 450-700nm
This is a 25.4 mm diameter Plano-Concave lens, manufactured by Qioptiq Photonics, a renowned name in the field of precision optics. The lens is made of N-BK7, a popular glass type known for its excellent optical properties, especially in the visible spectrum.
The lens features a negative focal length (EFL) of -100mm, making it suitable for applications that require light convergence or divergence. The lens's concave surface has a radius of curvature (R1) of -51.212mm, further enhancing its light bending capabilities.
The lens is coated with Qio Bbar Arb2visnbk7, a broadband anti-reflection coating designed for use in the visible spectrum (450-700nm). This coating reduces surface reflections, improving light transmission and enhancing the overall performance of the lens.
The lens is mounted, providing convenience and ease of use. The center thickness of the lens is 1.5mm, ensuring minimal optical distortion. The lens's geometry is spherical, a common and reliable choice for many optical applications.
