An apparatus for localized transmittance measurements of optical coatings with spatially non-uniform performance is presented. The setup allows spectral acquisition in the range of 400-1000 nm with spatial resolution higher than 20 μm. Examples of its implementation for the characterization of linearly variable optical components of portable spectrometers are given. © 2010 Chinese Optics Letters.
