KPC037AR.16 25.4 mm Dia. x -75 mm FL; NIR coated; Plano-Concave Lens 650-1000nm
The KPC037AR.16 is a Plano-Concave Lens, a type of spherical lens, with a diameter of 25.4 mm and a focal length of -75 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 its diameter, thickness edge, and thickness center. The diameter is 25.4 mm, the thickness edge is 4.22 mm, and the thickness center is 2.5 mm. The effective focal length (EFL) is -75 mm, and the radius of curvature (R1) is -38.76 mm. The back focal length (BFL) is -76.64 mm, and both the inner and outer radii are 0 mm.
The lens features a New AR-16 coating on both the front and back surfaces, designed for the near-infrared (NIR) region of the spectrum, specifically for wavelengths between 650 and 1000 nm. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall system's efficiency.
