49-922-INK 20.0mm Dia. x 55.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 49-922-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 20.0mm, is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically catering to wavelengths between 400-1000nm.
The lens features a front and back coating of edm visnir0sp2002000, which is an in-house coating developed by Edmund Optics. This coating enhances the lens's performance in the VIS-NIR spectrum, providing improved transmission and reduced reflection.
The lens's geometry is characterized by its edge thickness of 1.48mm and center thickness of 4.5mm. The effective focal length (EFL) of the lens is 35mm, and the radius of curvature (R1) is 18.09mm. The back focal length (BFL) is 32.04mm, and the lens does not have an inner or outer radius.
The material ID of the lens is n-bk7 schott, which is a high-quality optical glass known for its excellent transparency and low dispersion. This makes the lens suitable for a wide range of applications, including imaging, beam shaping, and light collimation.
According to the vendor's website, the lens is currently in stock, indicating its availability for immediate purchase and use.
