率も限度があった。Conventional technology Conventional diamond anvil cells were originally used for other physical property measurements (X-ray diffraction, absorption spectra, Raman spectra, etc.)
It was developed with the purpose of In order to generate higher pressures, it is necessary to design the pressure vessel to make the support part of the anvil as strong as possible. For this reason, in conventional diamond anvil cells, the observation window for sample observation has a minimum necessary size, for example, the outer opening is large and has a diameter of 1.
The sample is located deep, and the distance from the outer surface of the cell body to the sample is approximately 10 mm at the shortest.
Only objective lenses with longer working distances could be used in the barrel. An objective lens with a long working distance generally has a low magnification, and the long working distance objective lens with the highest magnification applicable to a conventional diamond anvil cell has a magnification of 25 times (working distance 15 mm). Therefore, there was a limit to the magnification that could be observed.

By configuring the cell so that the end is pushed by a bellows and making the entire cell thinner, the objective lens can be brought closer to the sample, making it possible to use a high-magnification microscope with an objective lens with a short working distance.

Diamond anvils 1 are each fixed, and high pressure is generated between the diamond anvils by pushing the other end of the plate with a bellows 11. For example, when attempting to observe crystal growth from an aqueous solution under high pressure using a microscope, a metal gasket is placed on top of the lower diamond anvil, the sample solution is poured into a hole in the center of the gasket, and the sample solution is poured into the hole in the center of the gasket. After sandwiching, pressure is applied between the diamond anvils. This deforms the gasket, transmits pressure to the solution, and grows crystals, which are observed under a microscope through a diamond anvil.
