KPX229AR.18 76.2 mm Dia. x 200 mm FL; IR coated; Plano-Convex Lens IR 1000-1550nm
The KPX229AR.18 is a Plano-Convex Lens, a type of spherical lens, sourced from MKS/Newport. This lens boasts a diameter of 76.2 mm and a focal length of 200 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 high homogeneity.
The KPX229AR.18 features a New AR-18 coating on both the front and back surfaces. This anti-reflective coating is specifically designed for the infrared spectrum, enhancing transmission within the 1000-1550nm range. The coating reduces surface reflections, thereby improving the overall efficiency and performance of the lens.
The lens has a thickness of 3 mm at the edge and 10.27 mm at the center. The inner radius is 0, and the back focal length is 193.22 mm. The radius of curvature of the first surface (R1) is 103.36 mm. This lens is available for purchase directly from the vendor's website, where it is currently listed as in stock.
