KPX187AR.18 50.8 mm Dia. x 100 mm FL; IR coated; Plano-Convex Lens IR 1000-1550nm
This is a Plano-Convex Lens, type KPX187AR.18, sourced from MKS/Newport. It is designed for use in the infrared spectrum, specifically between 1000nm and 1550nm. The lens has a diameter of 50.8mm and a focal length of 100mm, making it suitable for a variety of optical applications.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The base shape is circular, and the lens features a plano-convex geometry, meaning one side is flat while the other is curved. The edge thickness of the lens is 3mm, and the center thickness is 9.673mm.
The lens has an effective focal length (EFL) of 100mm and a back focal length (BFL) of 93.62mm. The inner radius of the lens is 0mm, and the radius of curvature (R1) is 51.68mm.
The lens is coated with New AR-18 fromfigure on both the front and back surfaces, enhancing its performance in the infrared spectrum. This coating reduces reflection and increases transmission, making the lens more efficient in its intended range.
