Guidance on Selecting Between Upright and Inverted Microscopes
Metallographic microscope, also known as material microscope, is mainly used to observe the structure of metal structure. It can be divided into upright metallographic microscope and inverted metallographic microscope
The upright metallographic microscope produces a positive image during observation, which brings great convenience to the user's observation and identification. In addition to analyzing and identifying metal samples with a height of 20-30mm, it is more widely used for transparent, semi transparent or opaque substances due to its conformity with human daily habits. Observing targets larger than 3 microns but smaller than 20 microns, such as metal ceramics, electronic chips, printed circuits, LCD substrates, films, fibers, granular objects, coatings, and other materials, can achieve good imaging effects for their surface structures and traces. In addition, the external camera system can be easily connected to the video screen and computer for real-time and dynamic image observation, saving and editing, printing, and combined with various software to meet the needs of more professional metallographic, measurement, and interactive teaching fields. Inverted metallographic microscope uses optical plane imaging to identify and analyze the microstructure of various metals and alloys. It is an important tool for studying metallography in metal physics and can be widely used in factories or laboratories for casting quality, raw material inspection, or research and analysis of material metallographic structure after process treatment. It provides intuitive analysis results and is a key equipment for quality identification and analysis of casting, smelting, and heat treatment in mining, metallurgy, manufacturing, and mechanical processing industries.
In recent years, due to the need for high magnification planar microscopy technology to support chip production in the microelectronics industry, metallographic microscopes have been introduced and continuously improved to meet the special needs of the industry. Inverted metallographic microscope, as the observation surface of the sample coincides with the surface of the worktable, the observation objective is located below the worktable and observed upwards. This observation form is not limited by the height of the sample, and is easy to use. The instrument structure is compact, the appearance is beautiful and generous, and the inverted metallographic microscope base has a large support area and a low center of gravity, which is stable and reliable. The eyepiece and support surface are tilted at 45 ℃, making observation comfortable.
