KPX190AR.16 50.8 mm Dia. x 125 mm FL; NIR coated; Plano-Convex Lens NIR 650-1000nm
The KPX190AR.16 is a Plano-Convex lens, sourced from MKS/Newport, with a diameter of 50.8 mm and a focal length of 125 mm. This lens is designed for use in the near-infrared spectrum, specifically between 650 and 1000 nm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens has a plano-convex geometry, meaning one side is flat (plano) and the other side is curved (convex). This design is often used to collimate or focus light, making it ideal for a wide range of applications.
The KPX190AR.16 features a New AR-16 coating on both the front and back surfaces. This anti-reflection coating is specifically designed to reduce surface reflections in the near-infrared region, enhancing the overall transmission of the lens. The edge thickness of the lens is 3 mm, while the center thickness is 8.203 mm.
The lens has an inner radius of 0, indicating it is a meniscus lens. The effective focal length (EFL) is 125 mm, and the back focal length (BFL) is 119.59 mm. The radius of curvature (R1) of the curved surface is 64.6 mm.
