KBX046AR.18 25.4 mm Dia. x 25.4 mm FL; IR coated; Double-Convex Lens IR 1000-1550nm
This is a high-quality double-convex lens, designed and manufactured by MKS/Newport, a renowned vendor in the optical industry. The lens, identified as KBX046AR.18, is a spherical lens with a base shape of a circle, featuring a diameter of 25.4 mm and a thickness at the edge of 3 mm. The center thickness is 10.132 mm, and the effective focal length (EFL) is 25.4 mm.
The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The curvature of the lens is defined by two radii, R1 and R2, which are 24.397 mm and -24.397 mm respectively. The back focal length (BFL) is 21.8 mm, and both the inner and outer radii are 0.
The lens is coated with New AR-18 fromfigure on both the front and back surfaces, enhancing its performance in the infrared spectrum, specifically between 1000nm and 1550nm. This coating reduces reflection and increases transmission, making it ideal for applications that require high-transmission optics.
