Calomel is suitable for the construction of acousto-optical devices. To illustrate, Calomel´s AO figure of merit is comparable with that of a tellurium dioxide TeO2 and more than one order better than that of lead molybdenate PbMoO4. The transparency of Calomel (0.38 to 20µm) enables the use of AO units in a broad spectral range (compared with TeO2) covering a very interesting thermal IR region. No acousto-optical tuneable filter for interesting spectral TIR region is currently available on the market.
