KPX099AR.18 25.4 mm Dia. x 138 mm FL; IR coated; Plano-Convex Lens IR 1000-1550nm
The KPX099AR.18 is a Plano-Convex Lens, a type of spherical lens, sourced from MKS/Newport. This lens boasts a diameter of 25.4 mm and a focal length of 138 mm, making it suitable for a wide range 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 specifically designed to reduce reflection and increase transmission in the infrared region, between 1000 and 1550 nanometers. This makes the lens ideal for use in IR spectroscopy, thermal imaging, and other applications where high transmission in the IR region is required.
The lens has a thickness of 3 mm at the edge and 4.136 mm at the center. The inner radius is 0, indicating a plano surface on the opposite side of the convex surface. The effective focal length (EFL) is 138 mm, and the radius of curvature (R1) is 71.583 mm. The back focal length (BFL) is 135.28 mm.
