G052206322 12.7 mm Dia. N-BK7 Mounted Double-Convex Lens; EFL=20mm 450-700nm
This is a G052206322 lens, a high-quality optical component manufactured by Qioptiq Photonics. The lens boasts a 12.7 mm diameter and is made of N-BK7, a popular glass type in the optical industry known for its excellent optical properties.
The lens is a mounted double-convex spherical lens, meaning it has two convex surfaces that curve outwards. This design is often used to converge light rays to a single point, making it ideal for various applications such as imaging and beam shaping. The lens has an effective focal length (EFL) of 20mm, which is the distance from the lens's center to the point where the light rays converge.
The lens's geometry is also noteworthy. It has a thickness of 0.9mm at the edge and 3mm at the center. The radii of curvature for the first and second surfaces are 20.097mm and -20.097mm, respectively. The lens is designed to operate within the wavelength range of 450-700nm, which covers the visible light spectrum.
The lens is coated with qio bbar arb2visnbk7 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency and quality of the optical system.
