KBX178AR.16 50.8 mm Dia. x 500 mm FL; NIR coated; Double-Convex Lens NIR 650-1000nm
The KBX178AR.16 is a high-quality double-convex lens, designed for use in the near-infrared spectrum, specifically between 650 and 1000nm. This lens, sourced from MKS/Newport, is a spherical lens with a base shape of a circle, featuring a diameter of 50.8mm and a focal length of 500mm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The geometry of the lens includes a thickness of 3mm at the edge and 4.251mm at the center, with an effective focal length (EFL) of 500mm. The first radius of curvature (R1) is 516.098mm, while the second radius (R2) is -516.098mm, indicating the double-convex nature of the lens. The back focal length (BFL) is 498.59mm.
The KBX178AR.16 is coated with New AR-16, a coating specifically designed for the near-infrared spectrum. This coating is applied to both the front and back surfaces of the lens, enhancing its performance in the specified wavelength range.
