Ⅰ Use:
      Measuring microscope is one of optical measure instruments. With simple structure and convenient operation, this instrument is widely used and the main use is as following:
1. Rectangular coordinate measures length, example: hole distance, base level distance, reticle width, key slit width, slit width, inner and outer circle diameter, etc.
2. Rotary dial measures angel, example: dial, sampler, gauge, drilling templet, and other parts with complicated geometrical shape.
3. Used as observing microscope to examine surface cleanness, appraisal ore sample in metallurgy industry, appraisal printing photoengraving, examine weave fiber etc. in comparative method.
