With this module, the TPS spectra 3000 can perform XY transmission mapping. The motor driven module allows transmission spectra to be collected at different points on the sample. Spectral variations across the sample can be identified and by using TeraView’s TPI imaging software, images of pulse intensity variation or spectral mapping can be preformed. The maximum scan area is 19mm x 19mm with a point spacing of between 50 and 500 microns. Spectral averaging is also possible.
