Common Misuses of Five Types of Microscopes
1. Place the microscope in the laboratory sink or by the window. Moisture and dust are both killers of the microscope. Improper placement and location can greatly shorten the lifespan of the microscope.
Beginners of microscopes have little understanding of their basic principles and structures, and rough manipulation can also be a fatal flaw of microscopes. For example, frequent movement, excessive force when picking and placing, using force to lift and lower the focusing system during focusing, inability to adjust the focal length and pupil distance correctly, and so on.
3. The working distance of high-power lenses is usually very short, and improper operation can also damage the high-power lenses. For example, if an operator does not clean or wipe the 100X oil lens after use, it is a bad usage habit.
4. When changing the objective lens, operators often directly turn the animal lens, unaware that this operation will affect the coaxiality and focus of the optical axis. The correct usage method is to rotate the objective lens converter to obtain the desired observation objective lens.
5. Setting the spotlight or field of view light bar too large or too small, or adjusting its position too high or too low, will not result in microscopy images with optimal resolution and sharpness. In short, it is important to use a microscope to obtain the best microscopic images, and to learn and observe more in order to become a master of the microscopic world.
When disassembling the eyepiece and spotlight, the following points should be noted:
a, circumspect.
b, When disassembling, it is necessary to mark the relative position of each component (which can be marked by drawing lines on the shell), the relative order, and the front and back of the lens to prevent errors during reassembly.
c, The operating environment should be kept clean and dry. When disassembling the eyepiece, simply unscrew the upper and lower lenses from both ends. The field of view light bar inside the eyepiece cannot be moved. Otherwise, it will blur the boundary of the field of view. It is strictly prohibited to further disassemble the lens on the spotlight after it is turned off. Due to the oil immersed lens on it, it undergoes good sealing before leaving the factory, and further disassembly can damage its sealing performance and cause damage.
