KPX199AR.18 50.8 mm Dia. x 200 mm FL; IR coated; Plano-Convex Lens IR 1000-1550nm
The KPX199AR.18 is a Plano-Convex Lens, a type of spherical lens, sourced from MKS/Newport. This lens boasts a diameter of 50.8 mm and a focal length of 200 mm, making it suitable for a wide range of optical applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The KPX199AR.18 features a New AR-18 coating on both the front and back surfaces. This anti-reflective coating is specifically designed for the infrared spectrum, enhancing transmission within the 1000-1550 nm range. The coating reduces surface reflections, thereby improving the overall efficiency and performance of the lens.
The lens has a thickness of 3 mm at the edge and 6.17 mm at the center. The inner radius is 0 mm, indicating a plano surface on one side. The lens's effective focal length (EFL) is 200 mm, and the radius of curvature (R1) is 103.36 mm. The back focal length (BFL) is 195.93 mm.
