KPC070AR.16 50.8 mm Dia. x -200 mm FL; NIR coated; Plano-Concave Lens 650-1000nm

The KPC070AR.16 is a Plano-Concave Lens with a diameter of 50.8 mm and a focal length of -200 mm, specifically designed for use in the near-infrared (NIR) spectrum, spanning 650-1000nm. This lens is sourced from MKS/Newport, a reputable vendor in the optical industry.

The lens is made from N-BK7 Schott, a popular material for optical elements due to its excellent optical properties and versatility. The lens features a plano-concave geometry, meaning one side is flat while the other is curved inward. This design is ideal for applications requiring light collimation or reduction of beam divergence.

The KPC070AR.16 is coated with New AR-16 fromfigure on both the front and back surfaces. This anti-reflective coating enhances the lens' performance by reducing surface reflections, thereby increasing transmission and improving overall system efficiency. The coating is specifically designed for the NIR spectrum, ensuring optimal performance in its intended use range.

The lens has a thickness of 5.06mm at the edge and 2.5mm at the center, providing a robust and durable structure. The inner and outer radii are 0mm, indicating a simple, straightforward design. The lens's geometry is spherical, a common and reliable choice for many optical applications.
