Measure the N.A. of Fibers

The fundamental parameters of fibers include something called the N.A.. The illustration below shows a system which determines the N.A. of a fiber instantaneously and in two dimensions, using an FFP optics. The angle distribution of the fiber output beam is converted to a position distribution using the A3267-12 FFP optics, and is then imaged using a camera.The camera output is measured and analyzed using the LEPAS-11 to determine the N.A.. The C5948-71 CCD camera for laser measurement is used to measure multi-mode fibers, while the C5840-10 near infrared camera, which is quantitative in the infrared range, is used to measure single-mode fibers.
