49-921-INK 20.0mm Dia. x 25.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 49-921-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 spectrum, specifically between 400-1000nm. The lens has a front thickness of 1.26mm and a center thickness of 4mm, making it a robust and reliable choice for various optical applications.
The lens's effective focal length (EFL) is 25mm, which is a crucial parameter in lens selection. The front and back surfaces of the lens are coated with edm visnir0sp2002000, a specialized coating that enhances its performance in the VIS-NIR range.
The lens's inner and outer radii are 0mm, indicating a flat inner surface and a curved outer surface. The radius of curvature (R1) of the outer surface is 19.62mm. The back focal length (BFL) of the lens is 22.76mm.
This lens is made from n-sf11 schott, a high-index material often used in optical applications due to its excellent dispersion characteristics. The lens's geometry and material properties make it suitable for use in a wide range of applications, including imaging, beam shaping, and light collimation.
According to the vendor's website, the lens is currently in stock, making it an immediately available option for those in need of a high-quality, VIS-NIR lens.
