G311308322 22.4 mm Dia. N-BK7 Double-Convex Lens; EFL=25mm 450-700nm
This is a G311308322 double-convex lens, sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics. The lens has a base shape of a circle and a diameter of 22.4 mm, making it suitable for a wide range of optical applications.
The lens features a significant thickness, with 1.6 mm at the edge and 7 mm at the center. The effective focal length (EFL) is 25 mm, which is a common choice for many optical systems. The lens is designed to work within the wavelength range of 450-700 nm, covering the visible light spectrum.
The lens is made of N-BK7, a popular type of glass due to its excellent optical properties. This material is known for its low auto-fluorescence, making it ideal for applications where minimal background noise is crucial.
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 of the optical system.
