G311320400 22.4 mm Dia. N-BK7 Double-Convex Lens; EFL=200mm
This is a G311320400 lens, a high-quality optical component manufactured by Qioptiq Photonics. It is a double-convex spherical lens with a base shape of a circle, designed for use in a wide range of optical systems. The lens has a diameter of 22.4 mm and a thickness of 2.4 mm at the edge, with a center thickness of 3 mm.
The lens is made from N-BK7, a popular optical glass type known for its excellent optical properties. It has a focal length of 200 mm (EFL), making it suitable for applications that require moderate magnification. The lens features a front and back coating of qio silver ragv 45, which enhances its light transmission capabilities and resistance to environmental factors.
The lens's geometry, specifically its curvature, is defined by two radii: R1 is 209.83, and R2 is -209.83. This specific curvature design allows for a wide range of optical applications. The lens is designed to operate at a wavelength of 587.6 nm.
