KPX121AR.16 25.4 mm Dia. x 750 mm FL; NIR coated; Plano-Convex Lens NIR 650-1000nm
The KPX121AR.16 is a Plano-Convex lens, a type of spherical lens, with a diameter of 25.4 mm and a focal length of 750 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 lens's geometry is characterized by a thickness of 3 mm at the edge and 3.208 mm at the center. The inner radius is zero, indicating a plano surface on one side and a curved surface on the other. The radius of curvature of the curved surface is 387.6 mm, and the back focal length is 747.88 mm.
The KPX121AR.16 lens 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 650-1000 nm. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving overall system efficiency.
