Spectrophotometer for measuring transmission spectra

摘要

In a spectrophotometer for measuring transmission spectra, the holder with a test sample is disposed inside the double monochromator between the intermediate slit and the second dispersive element and is capable of moving across the propagation path of the light flux at the output of the intermediate slit for placing the test sample in the path of the light flux and removing the sample from the path of the light flux.
