Paper Abstract

We present a new approach of measuring the spectral transmission ratio of a lens under test (LUT). Three auxiliary optics are used to perform this test, including one focusing lens, one small prism, and one reflecting mirror, whose transmission or reflection properties need not be known. This method is able to measure the lens transmission ratio over the entire visible spectrum range, and covers a large portion of the lens pupil aperture.
