KPX211AR.16 50.8 mm Dia. x 500 mm FL; NIR coated; Plano-Convex Lens NIR 650-1000nm

The KPX211AR.16 is a Plano-Convex lens, a type of spherical lens, with a diameter of 50.8 mm and a focal length of 500 mm. This lens is sourced from MKS/Newport, a renowned vendor in the optical industry. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.

The KPX211AR.16 features a New AR-16 coating on both the front and back surfaces. This anti-reflective coating is specifically designed for the near-infrared (NIR) spectrum, enhancing transmission within the 650-1000nm range. This coating reduces surface reflections, improving the overall efficiency and performance of the lens.

The lens has a thickness of 3 mm at the edge and 4.251 mm at the center. The inner radius is 0 mm, indicating a plano surface on the other side of the lens. The effective focal length (EFL) is 500 mm, and the radius of curvature (R1) is 258.4 mm. The back focal length (BFL) is 497.19 mm.

This lens is ideal for applications that require high-quality imaging or light transmission in the near-infrared spectrum. Its robust construction, high-quality materials, and advanced coating make it a reliable choice for various optical systems.
