Using a microscope micrometer
Believe that the use of most users of the microscope microscope micrometer is not very familiar with, so I will use a microscope micrometer shows up, now put out for the majority of users of the microscope study, we hope to help.
Micrometer is used to object size, the length of the measured measuring microscope field tools, including the eyepiece micrometer (graticule eyepiece micrometer scale) and taiwan. When used together with. Microscope eyepiece micrometer eyepiece system in the focal plane of the lens and is provided with a scale, the scale value for each 0.1mm, micrometer table ruler for a special slide, the central scale, each a small lattice value is 0.01mm (10um), when in use, the eyepiece micrometer is inserted into the eyepiece pipe, rotating front lens will scale adjustable eyepiece in clear, in the micrometer table feet on the stage, the focusing point to see the scale platform scale. When the first two observation scale overlap completely from the "0" points out, right at two feet and where overlap, and then write down two feet overlapping cell number, in order to calculate the micrometer each small lattice in the magnification of the actual size.
Calculation method:
Formula: X number of 10 overlapping grid ruler
Project scale overlap cell number
For example: a small lattice and micrometer eyepiece micrometer Taiwan ruler on the eighth overlapping =8 * 10
The eyepiece micrometer on each small lattice: 16um= (8 × 10) /5
No longer using micrometer station measurements, such as changing the microscope magnified the odds, it is necessary to calibrate the eyepiece micrometer again.
