Abstract
This paper describes a setup for measuring fiber N.A. by optical spot technique using M
416B
refractive index analyzer with some additional optical components. By using this approach
large injected optical power
symmetrical circular spot and high definition edge can be obtained.The measured results are in good agreementwith that measured by typical measurement method.
