Abstract

A compact opto-mechanical setup has been developed for the precise characterization of optical filters with spatially varying spectral responses. Combining high spatial resolution and low-divergence illumination with high dynamic range detection, the instrument enables accurate and spatially resolved measurement of spectral transmission properties of butcher block filters in both their pass band and stop band.
