The overall functions of a measuring microscope
As early as the first century BC, people discovered that by observing tiny objects through a spherical transparent object, they could be magnified and imaged. Later, they gradually understood the rules that the spherical glass surface could magnify the object. A measuring microscope is an instrument that uses transmission and reflection to make precise measurements of the length and angle of a workpiece, especially suitable for testing instruments such as video heads, large-scale integrated circuit linewidths, and other precision parts. So what are the overall functions of a measuring microscope? Let me introduce it to you below.
The overall functions of a measuring microscope are as follows:
1. Measure length in rectangular coordinates.
2. Measure angles with a rotating dial.
3. Used as an observation microscope.
4. Use the movement of the measuring microscope's micro-moving load platform and the full eyepiece's cross-coordinate lines to measure length.
5. Use the differential angle dial of the rotating load platform and the eyepiece's full-coordinate line to measure angles. Align one end of the angle to be measured with the cross line and let the other end also align.
6. Measure the pitch, diameter, outer diameter, tooth angle, and tooth shape of standard test threads.
7. Inspect the crystal grain status on the metallographic surface.
8. Inspect the surface condition of the workpiece.
9. Check whether the size or contour of small parts matches the standard sample.
The above is an introduction to the overall functions of a measuring microscope. The optical components of a measuring microscope include an eyepiece, an objective lens, a glass workbench, etc. The surface of the optical components can be cleaned with a mixture of a small amount of alcohol and ether dipped in degreased cotton, but do not rub the lenses. Moreover, the measuring microscope should be used correctly and reasonably arranged. The storage location of the instrument should avoid dust, humidity, sudden temperature changes, or gas environments containing acid and alkali.
