Differences Between Upright Microscopes and Inverted Microscopes
Due to the different properties of the observed objects, there are significant differences in the selection of microscopes. The most commonly used ones in daily work are ordinary upright microscopes and inverted microscopes. The differences between upright microscopes and inverted microscopes are as follows:
The upright microscope is the most common type in laboratories and classrooms. Its objective turret faces downward, and the stage is located below the objectives. When observing an object, place the sample on the stage, and the objectives approach the slide from above for observation. It has a short working distance and is suitable for observing sections, etc.
The inverted microscope has upward-facing objectives, with the stage positioned above the objectives. It is most suitable for observing living cells. This is because the upright biological microscope has a very short working distance, making it impossible to observe living cells in petri dishes. In contrast, the inverted microscope operates differently: simply place the petri dish on the stage to conduct observation. Thanks to its reversed optical path-with the condenser located above-and long working distance, it can easily observe living cells inside petri dishes.
Inverted metallographic microscope is an important instrument for studying metallurgy, mainly used for identifying and analyzing the internal structure and structure of metals. Inverted metallographic microscope can be used for quality research in casting, smelting, heat treatment, inspection of raw materials, or analysis after material treatment.
The inverted metallographic microscope system is an organic combination of traditional optical microscopes and computers (digital cameras) through photoelectric conversion. It can not only perform microscopic observations on the eyepiece, but also observe real-time dynamic images on the computer (digital camera) display screen, and edit, save, and print the required images.
When operating an inverted metallographic microscope, the observation surface of the sample is downward and coincides with the worktable, and there is no requirement for the height and parallelism of the sample, making it suitable for irregularly shaped or larger samples. Inverted metallographic microscopes are widely used in factories, laboratories, teaching, and scientific research fields.
