KPX202AR.18 50.8 mm Dia. x 250 mm FL; IR coated; Plano-Convex Lens IR 1000-1550nm
The KPX202AR.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 250 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 KPX202AR.18 features a New AR-18 coating on both the front and back surfaces. This anti-reflective coating enhances the lens's performance in the infrared spectrum, specifically between 1000nm and 1550nm. The coating reduces surface reflections, thereby improving transmission and increasing the lens's overall efficiency.
The lens's geometry is another notable feature. It has an edge thickness of 3 mm and a center thickness of 5.521 mm. The inner radius is 0, and the radius of curvature (R1) is 129.2 mm. The back focal length (BFL) is 246.36 mm, and the effective focal length (EFL) is 250 mm.
