Abstract
This paper is devoted to the presentation of a new spectrophotometric system that allows us for the accurate measurement of the transmission of thin-film filters over an ultra-wide optical density range (from 0 to 11) between 400 nm and 1000 nm. After a detailed description of its structure, we define the transmission range reachable to this set-up and we quantify the influence of the spectral profile of the source on this critical feature. A qualification of this bench, including a determination of its noise floor, is performed on a dedicated band- pass filter manufactured by Institut Fresnel, and we conclude by the presentation of results of ultra-wide range transmission measurements achieved on commercially available filters (long-pass, short-pass, and notch).
