Optical Pyrometer - CellaCrystal® PA 64 (500 – 1400 °C)

The CellaCrystal PA 64 has been developed for optical temperature measurement when growing crystals with the plasma-assisted CVD process. Thanks to the two-colour measuring method and the special wavelength, the measurement is minimally influenced by the plasma. Combined with the constant high resolution of < 0.1 K over the entire measuring range and the very high long-term stability, the device meets the requirements for the necessary high measuring accuracy. With the help of the through-the-lens sighting, laser pilot light or video camera, the pyrometer can be precisely aligned to the measuring point.
