KPX025AR.18 6.35 mm Dia. x 50.2 mm FL; IR coated; Plano-Convex Lens IR 1000-1550nm

The KPX025AR.18 is a Plano-Convex Lens, a type of spherical lens, sourced from the renowned optical components manufacturer, MKS/Newport. This lens, with a diameter of 6.35 mm, is designed for use within the infrared spectrum, specifically between 1000nm and 1550nm.

The lens features a plano-convex geometry, meaning one side is flat (plano) while the other side is curved (convex). The curvature of the convex side is defined by a radius of 25.943 mm, and the lens has a center thickness of 3.195 mm. The edge thickness of the lens is 3 mm. The effective focal length (EFL) of the lens is 50.2 mm, and the back focal length (BFL) is 48.09 mm.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is coated with New AR-18, a broadband anti-reflective coating that enhances transmission and reduces surface reflections, ensuring optimal performance in the intended infrared spectrum.
