What are the main uses of optical microscope?

Optical microscopes mainly include binocular stereo microscope, metallographic microscope, ultraviolet fluorescence microscope, TV microscope, charge-coupled microscope and scanning microscope. Their respective purposes are:

1, binocular stereomicroscope is widely used in biological and medical fields for slicing and microsurgery; It is used for the observation, assembly and inspection of micro parts and integrated circuits in industry.

2. Metallographic microscope is specially used to observe the metallographic structure of opaque objects such as metals and minerals. These opaque objects can't be observed under ordinary transmission light microscope, so the main difference between metallographic microscope and ordinary microscope is that the former is illuminated by reflected light, while the latter is illuminated by transmitted light.

3. Ultraviolet fluorescence microscope is used in biological and medical fields. Some specimens can't perceive the structural details under visible light, but after dyeing, under ultraviolet light irradiation, visible light can be emitted due to fluorescence, forming a visible image. This kind of microscope is often used in biology and medicine.

4. TV microscope and CCD microscope can be combined with computer, which is convenient to realize the automation of detection and information processing, and is often used in situations where a lot of complicated detection work is needed.

5, scanning microscope is suitable for high resolution occasions. In the scanning microscope, the highest resolution of the objective lens is ensured by narrowing the field of view, and at the same time, the imaging beam is scanned in a large field of view relative to the object surface by optical or mechanical scanning. This microscope is suitable for observing large-field images that require high resolution. Coarse focusing screw: adjust the lens barrel up and down in a large range.
