Ⅰ. USE FIELD
The instrument is easy to operate and useful. You can observe kinds of mineral's crystal
figure, color, interference color, and even identify their optical performance exactly. It is used so
widely that you can see it in everywhere just like geology, petroleum, coal, chemical fiber, medical
treatment and physicinspection and so on. You can also find it in academic demonstration and
research.
