KPX103AR.18 25.4 mm Dia. x 175 mm FL; IR coated; Plano-Convex Lens IR 1000-1550nm
The KPX103AR.18 is a Plano-Convex Lens, a type of spherical lens, sourced from MKS/Newport. This lens has a diameter of 25.4 mm and a focal length of 175 mm, 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 relatively low cost.
The lens features a new AR-18 coating on both the front and back surfaces. This anti-reflective coating is designed to reduce surface reflections and increase transmission in the infrared region, specifically between 1000 and 1550 nm. The coating ensures that the lens performs optimally in its intended spectral range, making it an ideal choice for infrared applications.
The geometry of the lens includes a thickness of 3 mm at the edge and 3.896 mm at the center. The inner radius is 0, indicating a plano surface on one side and a curved surface on the other. The effective focal length (EFL) is 175 mm, and the radius of curvature (R1) is 90.44 mm. The back focal length (BFL) is 172.43 mm.
