G063012525 31.5 mm Dia. N-BK7 Mounted Double-Convex Lens; EFL=40mm 725-1050nm
This is a mounted double-convex lens with a diameter of 31.5 mm, sourced from Qioptiq Photonics. The lens is made of N-BK7, a type of glass commonly used in optical systems due to its excellent optical properties. The lens features a double-convex geometry, meaning it has two spherical surfaces that curve outwards, designed to focus light onto a single point.
The lens has an effective focal length (EFL) of 40 mm, which is the distance between the lens and the point where it focuses light. This makes it suitable for applications that require moderate magnification. The lens's thickness at the edge is 2.1 mm, while its center thickness is 8.3 mm, providing structural rigidity and stability.
The lens is coated with qio bbar arb2nirnbk7 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it more efficient in transmitting light. The lens is designed to operate within the wavelength range of 725-1050 nm, making it suitable for near-infrared applications.
