KPX109AR.16 25.4 mm Dia. x 250 mm FL; NIR coated; Plano-Convex Lens NIR 650-1000nm
The KPX109AR.16 is a Plano-Convex lens, a type of spherical lens, with a diameter of 25.4 mm and a focal length of 250 mm. This lens is sourced from MKS/Newport, a renowned vendor in the optical industry. The lens is designed for use in the near-infrared (NIR) spectrum, specifically between 650 and 1000 nanometers.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The geometry of the lens includes a thickness of 3 mm at the edge and 3.626 mm at the center. The inner radius is 0, indicating a plano surface on that side. The lens's effective focal length (EFL) is 250 mm, and the back focal length (BFL) is 247.61 mm.
The lens features a New AR-16 coating on both the front and back surfaces. This anti-reflective coating is specifically designed to reduce reflections in the NIR spectrum, enhancing the lens's performance in its intended use range. The lens's base shape is circular, making it suitable for a wide range of optical applications.
