G313210525 10 mm Dia. N-BK7 Double-Concave Lens; EFL=-10mm 725-1050nm
This is a G313210525 10 mm Dia. N-BK7 Double-Concave Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens is designed for use in the 725-1050nm wavelength range, making it suitable for a wide range of applications in the optical spectrum.
The lens is spherical in shape, with a base shape of a circle. It has a diameter of 10 mm and a center thickness of 1 mm, providing a compact and efficient design. The lens features a double-concave geometry, with radii of curvature of -10.669 mm for the first surface and 10.669 mm for the second surface. This geometry results in a negative focal length (EFL) of -10 mm, making it a converging lens.
The lens is made from N-BK7, a popular optical glass from Schott. This material is known for its excellent optical properties, including a high refractive index and low dispersion. The lens is unmounted, providing flexibility in its integration into optical systems.
The lens is coated with a broadband anti-reflection coating, specifically the Qio Bbar Arb2nirnbk7 coating, on both the front and back surfaces. This coating reduces reflection losses, enhancing the transmission of light through the lens. The coating is designed to operate over a wide wavelength range, from 725 to 1050 nm, making it suitable for use in broadband optical systems.
