The PMA-11 is a spectral analyzer that integrates a spectrograph and high performance multi-channel photodetector in a single compact chassis. Light collection is simplified through the use of optical fiber. The diffraction grating of the spectrograph and multi channel photodetector are rigidly fixed, resulting in excellent wavelength reproducibility. The wavelength axis and spectral response characteristics are calibrated at the factory, so that spectral measurements can be carried out easily and accurately.
