KPX217AR.18 50.8 mm Dia. x 1000 mm FL; IR coated; Plano-Convex Lens IR 1000-1550nm
The KPX217AR.18 is a Plano-Convex Lens, a type of spherical lens, with a diameter of 50.8 mm and a focal length of 1000 mm. This lens is sourced from the reputable vendor MKS/Newport and is currently in stock, as indicated by its weblink status.
The lens is made from the material n-bk7 schott, a popular choice in the optical industry due to its excellent optical properties. The geometry of the lens includes an edge thickness of 3 mm and a center thickness of 3.625 mm. The effective focal length (EFL) is 1000 mm, and the radius of curvature (R1) is 516.8 mm. The back focal length (BFL) is 997.61 mm, and the inner radius is 0 mm.
The KPX217AR.18 lens features a new AR-18 coating on both the front and back surfaces, enhancing its performance in the infrared spectrum, specifically between 1000-1550nm. This coating reduces reflection and increases transmission, making it ideal for applications that require high-quality imaging or light transmission in the infrared range.
