KPX226AR.18 76.2 mm Dia. x 150 mm FL; IR coated; Plano-Convex Lens IR 1000-1550nm
The KPX226AR.18 is a Plano-Convex Lens, a type of spherical lens, manufactured by MKS/Newport. This lens, with a diameter of 76.2 mm, is designed for use in the infrared spectrum, specifically between 1000nm and 1550nm.
The lens features a plano-convex geometry, meaning one side is flat (plano) and the other is curved (convex). The curvature of the convex side has a radius of 77.52 mm. The lens's thickness at the edge is 3 mm, while its center thickness is 13.009 mm. The effective focal length (EFL) of the lens is 150 mm, and the back focal length (BFL) is 141.42 mm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens's front and back surfaces are coated with New AR-18, a broadband anti-reflective coating designed for use in the infrared spectrum.
This lens is a great choice for applications that require a high-quality lens in the infrared spectrum, such as thermal imaging, night vision, and other infrared-based technologies.
