Definition of an inverted metallographic microscope
The inverted metallographic microscope is an important instrument for studying metallography. It is mainly used to identify and analyze the internal structure of metals. Inverted metallographic microscopes can be used for quality research in casting, smelting, and heat treatment, inspection of raw materials, or analysis after material processing.
The inverted metallographic microscope system organically combines a traditional optical microscope with a computer (digital camera) through photoelectric conversion. Not only can microscopic observations be made on the eyepiece, but also real-time dynamics can be observed on the computer (digital camera) display screen. images, and can edit, save and print the required pictures.
When operating the inverted metallographic microscope, the observation surface of the sample is downward and coincides with the work surface. There is no requirement for the height and parallelism of the sample. It is suitable for samples with irregular or large shapes. Inverted metallographic microscopes are widely used in factories, laboratories, teaching and scientific research and other fields.
Inverted metallographic microscope phase contrast observation method
1. Turn on the computer and connect the power supply. Turn on the electronic control switch at the lower end of the scope.
2. Place the object to be observed on the stage. Rotate the three-hole converter to select a smaller objective. Observe and adjust the hinged binocular eyepieces for comfort.
3. Adjust the light source: Push and pull the brightness adjuster at the lower end of the mirror body to the appropriate setting. Adjust the size of the light source by adjusting the grating under the condenser.
4. Adjust the image distance: Turn the three-hole converter and select an objective lens with an appropriate magnification; replace and select an appropriate eyepiece; adjust the lift at the same time to eliminate or reduce the halo around the image and improve the contrast of the image.
5. Observation: Observe the results through the eyepiece; adjust the stage and select the observation field of view.
6. Turn off the machine, remove the observation object, and push and pull the light source brightness adjuster to the darkest level. Turn off the switch at the lower end of the scope and disconnect the power supply. Rotate the three-hole adapter so that the objective lens is placed on the underside of the stage to prevent dust from settling.
