The KPC040AR.16 is a Plano-Concave Lens, a type of spherical lens, with a diameter of 25.4 mm and a focal length of -50 mm. This lens is sourced from the reputable vendor MKS/Newport and is available for purchase on their website, currently listed as in stock.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens has a thickness of 5.17 mm at the edge and 2.5 mm at the center, providing a balanced structure for various applications.
The KPC040AR.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) region, covering the wavelength range of 650-1000nm. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving overall system efficiency.
