Polarizing Microscopy Precautions
In order to ensure the service life and reliability of the system, pay attention to the following items:
1. The laboratory should have three anti-conditions: shockproof (away from the source of shock), moisture-proof (use air conditioner, dryer), dust-proof (floor on the ground); power supply: 220V+-10%, 50HZ temperature: 0-40 degrees.
2. When adjusting the focus, be careful not to let the objective lens touch the sample, so as not to scratch the objective lens.
3. Do not switch the objective lens when the center of the round hole of the stage spacer is close to the center of the objective lens, so as not to scratch the objective lens.
4. Don't adjust the brightness suddenly, and don't be too bright, which will affect the service life of the bulb and also damage the eyesight.
5. For all (function) switching, the action should be light and in place.
6. Turn off the brightness to the minimum.
7. Non-professionals should not adjust the lighting system (filament position lamp), so as not to affect the image quality.
8. Pay attention to high temperature when replacing the halogen lamp to avoid burns; be careful not to directly touch the glass body of the halogen lamp with your hands.
9. When the machine is not in use, adjust the objective lens to the lowest state through the focusing mechanism.
10. When the machine is turned off and not in use, do not cover the dust cover immediately, and cover it after it cools down. Pay attention to fire prevention.
11. Optical components that are not frequently used are placed in a drying dish.
12. Non-professionals should not try to wipe the objective lens and other optical components. The eyepiece can be wiped with a cotton swab dipped in a 1:1 ratio (absolute alcohol: ether) mixed liquid, and then wiped. Do not use other liquids to avoid damage to the eyepiece.
