KPC028AR.16 25.4 mm Dia. x -200 mm FL; NIR coated; Plano-Concave Lens 650-1000nm
The KPC028AR.16 is a Plano-Concave Lens, part of the Spherical Lens category, sourced from the renowned vendor MKS/Newport. This lens boasts a circular base shape with a diameter of 25.4 mm and a thickness edge of 3.13 mm, ensuring robustness and durability. The lens's center thickness is 2.5 mm, contributing to its overall compact design.
The lens has an effective focal length (EFL) of -200 mm, making it suitable for applications requiring negative focal lengths. The front and back surfaces of the lens are coated with the new AR-16 coating, enhancing its performance in the near-infrared (NIR) spectrum, specifically between 650-1000nm. This coating reduces reflection and increases transmission, making it ideal for applications such as optical imaging, beam shaping, and laser systems.
The KPC028AR.16 is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The lens's geometry, including its inner and outer radii, is optimized for superior performance. The front surface radius (R1) is -103.36 mm, while the back focal length (BFL) is -201.64 mm.
