over-stage for thermodynamic studies under a microscope

摘要

The invention relates to a over-stage destiny the studies of phenomena transient in nature, for which the pressure and the temperature may vary over very wide ranges / p & & p & according to the invention, the plate has an outer jacket body 1 provided with optical windows 6, 7, a fluid-tight internal chamber 8 in which is defined a volume experimental 9 and comprising, in addition, two optical windows 15, 16, and means for fixing and or monitor the temperature and pressure in the three-dimensional volume. / p & & p & application in particular in geology, mineralogy, crystallography and physics of solids.
