SPX049AR.16 50.8 mm Dia. x 200 mm FL; NIR coated; Plano-Convex Lens NIR I 650-1000nm
The SPX049AR.16 is a Plano-Convex Lens, a type of spherical lens, with a diameter of 50.8 mm and a focal length of 200 mm. This lens is sourced from MKS/Newport, a renowned vendor in the optical industry. The lens is designed for use within the near-infrared (NIR) spectrum, specifically between 650 and 1000 nanometers, making it suitable for a wide range of applications in this spectral range.
The lens geometry is characterized by a thickness of 3 mm at the edge and 6.584 mm at the center. The inner radius is 0, indicating a plano surface on one side and a curved surface on the other. The radius of curvature of the curved surface is 91.8 mm, and the back focal length is 195.48 mm.
The lens is made from UVFS material with the ID 1965. The front and back surfaces of the lens are coated with the new AR-16 coating, which is specifically designed for use in the NIR spectrum. This coating enhances the lens's performance by reducing reflection and increasing transmission within the specified wavelength range.
