Operational rules of the association optical metallurgical microscope

Operating rules of metallurgical microscope

The metallographic microscope is a precision optical instrument. In order to ensure the normal function of the metallographic microscope system, this regulation is specially formulated.

The metallographic microscope is used by a dedicated person who is responsible for daily maintenance and maintenance. No one can debug the device without permission.

The operation steps of the metallurgical microscope system and the daily maintenance and maintenance precautions are as follows:

1. Microscope

1. Remove the dust cover and turn on the power.

2. Place the sample on the stage gasket and adjust the coarse / fine adjustment knob to adjust the focus until the observed image is clear.

3. Adjust the position of the stage, find the field of view to be observed, and perform metallographic analysis.

2. Computer and image analysis system

Turn the observation / photograph switching knob on the metallurgical microscope to the PHOT position, and the information observed in the metallurgical microscope will be converted to the video interface and camera, turn on the computer, and start the image analysis software to observe the Real-time images are collected and processed after finding the field of view to be observed.

3. Routine maintenance, maintenance and precautions

To ensure the service life and reliability of the system, pay attention to the following:

1. The laboratory should have three protection conditions: shockproof (away from the source), moisture-proof (use air conditioner, dryer), dustproof (floor on the ground); power supply: 220V ± 10%, 50HZ; temperature: 0 ° C-40 ° C.

2. When focusing, be careful not to make the objective lens touch the specimen to avoid scratching the objective lens.

3. Do not switch the objective lens when the center of the round hole of the stage gasket is far from the center of the objective lens, so as not to scratch the objective lens.

4. Brightness adjustment should not be large or small, too bright, affect the life of the lamp, and also damage your eyesight.

5. All (functions) switch, the action should be light and in place.

6. The brightness should be adjusted to the minimum when shutting down.

7. Non-professionals should not adjust the lighting system (filament position lamp), so as not to affect the image quality.

8. When replacing the halogen lamp, pay attention to high temperature to avoid burns; be careful not to directly touch the glass body of the halogen lamp with your hands.

9. When the camera is not in use, adjust the objective lens to the lowest state through the focusing mechanism.

10. When the machine is not in use, do not cover the dust cover immediately, and then cover it after cooling, pay attention to fire prevention.

11. Place infrequently used optical components in a drying dish.

12. Non-professionals should not try to wipe the objective lens and other optical components. The eyepieces can be dipped in a 3: 7 ratio (absolute alcohol: ether) mixed liquid with absorbent cotton swabs and wiped dry. Do not use other liquids to avoid damage to the eyepieces.
