At present, there are mainly domestic and imported microscopes on the market. Generally speaking, the price difference is several to ten times. It is mainly based on your current budget and purpose to decide whether to buy domestic or imported, low, medium and high-end The price of different microscopes ranges from a few thousand to tens of thousands of yuan.
If you are a pure hobby and don't want to spend too much money, buy a student type, but the types of microscopes available on the Internet are of different types and it is difficult to make a choice.
There are two main types of student microscopes: biological microscopes and stereo microscopes.
1. Biological microscope magnification is general: 40X, 100X, 400X, 1000X, the highest configuration can reach 2000 times (20X eyepiece and 100X objective lens)
The entry microscope does not need to be 1000 times and 2000 times so high. 400 times is enough, the eyepiece is 10X, and the objective lens is 4X/10X/40X. When the magnification reaches 1000 times, cedar oil is needed when using a 100X objective lens, and it needs to be cleaned, which requires high sample preparation and is not necessary.
For interest cultivation, you can buy electric light sources or reflector types.
Slightly older students, junior high school students are best to buy a single-tube mirror with a mirror, generally junior high school teaching use this type, if you buy high-end or other types, many parts and structures are different, yes Not going to textbooks can easily confuse students. It is best to configure a single-tube biological microscope with a moving ruler to facilitate sample movement.
Xingming optical single-tube biological microscope recommended configuration: eyepiece 10X, objective lens 4X/10X/40X, with moving ruler, reflector, five-hole diaphragm. This configuration is suitable for elementary and junior high school students.
If you just play it, you can buy an electric light source directly. If you plug it in, the field of view is still easier to see.
2. Stereo microscopes (stereomicroscopes, dissecting mirrors, solid microscopes) have two types: fixed magnification and continuous zoom The multiple is generally about 10X-50X.
The stereo microscope is not used for teaching. The stereo microscope has a small magnification and a strong sense of three-dimensionality. It is very suitable for beginners to cultivate interest. The sample does not need to be prepared, and the diameter of the specimen is observed under the microscope. Such as mosquitoes, salt, MSG, skin, hair, etc., can let beginners understand more of the microscopic world.
3. Take pictures of microscope images
The images formed by the microscope can be displayed on the computer through the electronic eyepiece or the microscope CCD. But the image clarity will be lost.
1) For better ones, you can buy a special microscope camera to connect to the computer, with software to take pictures, video, etc.;
2) Electronic eyepieces generally do not work well, and without software, they only have imaging and photographing functions;
3) You can also directly use the mobile phone to take pictures with the eyepiece.
