G313217400 22.4 mm Dia. N-BK7 Double-Concave Lens; EFL=-150mm
This is a G313217400 22.4 mm Dia. N-BK7 Double-Concave Lens, sourced from the renowned optical components manufacturer, Qioptiq Photonics. The lens, which has a double-concave structure, is designed for use with a wavelength of 588 nm and is made from N-BK7 glass, a popular choice for its excellent optical properties.
The lens has a diameter of 22.4 mm and a center thickness of 1.5 mm. The effective focal length (EFL) is -150 mm, indicating that it is a diverging lens. The first and second radii of curvature (R1 and R2) are -156.22 mm and 156.22 mm, respectively, which are symmetrically concave. The lens does not have an inner or outer radius.
The lens is coated with Qio Silver RAGV 45 on both the front and back surfaces, which enhances its performance in specific applications. The lens's shape is spherical, a common geometry for optical lenses.
