KPX091AR.18 25.4 mm Dia. x 88.3 mm FL; IR coated; Plano-Convex Lens IR 1000-1550nm
The KPX091AR.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 88.3 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 chemical durability.
The lens features a new AR-18 coating on both the front and back surfaces, which is specifically designed to reduce reflection and increase transmission in the infrared spectrum, between 1000 and 1550 nanometers. This coating enhances the lens' performance in IR applications, making it an ideal choice for systems operating in this range.
The KPX091AR.18 has a thickness of 3 mm at the edge and 4.803 mm at the center. The inner radius is 0, indicating a plano surface on the opposite side of the convex surface. The back focal length is 85.13 mm, and the effective focal length is the same as the focal length at 88.3 mm.
