Countermeasures for Earthquakes
To prevent the microscope from being slipped and shaken by the strong shake of an earthquake, we
recommend taking the following countermeasures:
Prepare four angle-shaped brackets as shown in the figure, and screw them onto the table so that the
microscope is held tight by the brackets. See the figure for the sizes of the brackets. The brackets
should be made of aluminum alloy, with a thickness of 5 mm or more.
We recommend the use of an anti-vibration table to eliminate the influences of the vibration of the
table.
The dimensions in the figure below are for brackets 5 mm thick. Figure out the layout and
dimensions of brackets on the table in a way that best fit your condition.
