When measuring the surface spectral reflectance of various reflectors, metals, plastics, etc. or the spectral transmittance of glass and plastics, the CHTR-100 Reflection/Transmission Test Chamber is mainly used to collect photometric and chromatic energy, and then send the measured light signal to the spectrometer or reflection-transmission photometer through optical fiber or photoelectric detector to obtain color parameters.

The CHTR-100 Reflection/Transmission Test Chamber needs to be used with the PH2000 Photometer (or LMS-9000 High Precision CCD Spectroradiometer) and DC3005 DC Power Supply.
