PMA-12 Photonic multichannel analyzer


The PMA-12 is a compact spectral measurement system that combines a spectrometer and optical detector into one unit. Because of the high sensitivity, spectra can easily be obtained in many applications, just by bringing the optical fiber close to the sample without the connection to a special light collection system. Since the spectrometer and photo-detector are manufactured with high machine accuracy, the PMA-12 is stable and can be used with confidence for long periods of time. The wavelength axis and spectral response characteristics are already calibrated, so spectral measurements can be carried out easily and accurately.

The C14880-01 realizes low stray light and enables highly accurate spectrum analysis by reviewing the optical layout. By using a sensor with a built-in cooling element, low noise and highly reproducible measurements have been achieved.
