Metallographic microscope is mainly used for metallographic analysis of the instrument, the main identification and analysis of various metals, alloy materials, non-metallic substance structure and integrated circuits, micro-particles, wire, fiber, surface spraying and other surface conditions, metallographic microscope is also widely used in metallurgy, casting, machinery, ships, quality inspection, schools, industrial and mining enterprise laboratories, To identify and analyze the structure of various metals and alloys.

When we use the metallographic microscope, we often encounter a variety of problems. For example, when observing, whether it is from the eyepiece or the computer imaging system, it is dark or dark, even if the brightness of the light source is adjusted to z, it is still unable to get the appropriate lighting brightness. So how should we solve the problem of the field of view of the metallographic microscope becoming black? The following is a small edition of Fulai to introduce you.

1, check whether the objective is rotated in place, if the rotation is not in place, then adjust the objective disk.

2. The color filter in the light path of the reflection lighting system is not pulled or is not rotated in place.

3. The polarizer in the light path of the reflection lighting system is not pushed and pulled in place. If it is not pushed and pulled in place, please push it to the correct position.

4, the polarizing device will affect the brightness of the observation, usually do not need to use the polarizing observation, it is necessary to pull the polarizer and polarizer out of the light path system.

5, if you need polarizing observation, the entire field of view is still all black, then flip the knob on the polarizer. At this time, due to the effect of the polarizer, the brightness of the field of view will be reduced, and even when it is orthogonal, it will appear all black.

6, inverted metallographic microscope encountered this problem, but also in accordance with the above steps to check, the position of the possible parts and description of the method is different, the method of eliminating the problem and the principle is the same.

Today's share is here first, want to know more about metallographic microscope information, please pay attention to our Fulai light technology official website to see.
