How much do you know about choosing a microscope?

How much do you know about choosing a microscope? Microscope is a relatively common optical instrument at present, but with the continuous expansion of the development of optical instruments in recent years, some familiar brands of microscopes have appeared on the market, and the quality is even more uneven, so how to choose a suitable microscope? Let’s find out with me below
.

1.
Before purchasing, understand what type of microscope is suitable for the sample you want to detect.
When observing the sample, you need to use a glass slide or a petri dish
.

When the sample is placed on a glass slide, an upright biological microscope should be used, and an inverted biological microscope should be used when using a petri dish
.

2.
Whether it is necessary to take pictures or analyze and process the mirror images of the microscope, if necessary, please purchase a trinocular biological microscope and choose a digital imaging system.
If not, please choose a binocular biological microscope
.

3.
Requirements for the observation method of the microscope
.

In addition to bright field observation (BF), if you have any of dark field (DF), phase contrast (PH), differential interference (DIC), relief contrast (RC), polarized light (POL), fluorescence (FL) for the microscope Or several kinds of requirements, please pay attention to choose a microscope with related functions
.

 　　4.
Know the difference between an upright microscope and an inverted microscope and purchase it
.

 　　Metallographic microscope, also known as material microscope, is mainly used to observe the structure of metal structure, which can be divided into upright metallographic microscope and inverted metallographic microscope
.

 　　The upright metallographic microscope is imaged as an upright image during observation, which brings convenience to the user's observation and identification.
In addition to the analysis and identification of metal samples with a height of 20 to 30 mm, because it is in line with people's daily habits, so Wider application for transparent, translucent or opaque substances
.

Objects larger than 3 microns and smaller than 20 microns, such as cermets, electronic chips, printed circuits, LCD substrates, films, fibers, granular objects, coatings and other surface structures and traces, can have good imaging effects
.

In addition, the external camera system can be easily connected to the video screen and computer for real-time and static and dynamic image observation, saving and editing, printing combined with various software to meet the needs of metallography, measurement, and interactive teaching
.

 　　The inverted metallographic microscope uses the method of optical plane imaging to identify and analyze the structure of various metals and alloys.
It is an important tool for metallographic research in metal physics.
It can be widely used in factories or laboratories for casting quality and raw material inspection.
, or the research and analysis of the metallographic structure of the material after processing, so as to provide intuitive analysis results, and it is the key equipment for quality identification and analysis of casting, smelting, and heat treatment in mining, metallurgy, manufacturing, and machining industries
.

 　　5.
Consider the purchase budget
.

According to the observation application, microscopes can be divided into general observation, clinical application and research grades
.

According to the brand, there are mainly domestic and domestic microscopes on the market.
Generally speaking, the price difference ranges from several times to ten times.
You can decide whether to buy domestic or domestic microscopes according to your existing budget
.

The price of different microscopes in low and medium ranges from several thousand yuan to tens of thousands of yuan
.

 　　The above is the relevant content about the choice of microscope.
I believe that everyone has a corresponding understanding of this after reading, and everyone can use it as a reference.
I hope it will be helpful to you
