SM-2016DM Digital Microscope 40X-400X Digital USB Microscoped
SM-2016DM digital usb microscope
Installation
a) Requirements for the working environment of the microscope:
1), room temperature: 0 degrees - 40 degrees, maximum relative humidity: 85%
2), high temperature: high temperature will cause the microscope to grow mold, mold, and damage the instrument
3) Avoid rotating the microscope in a dusty environment, and apply plastic when the microscope is not in use.
cover to cover it.
4) The digital usb microscope should be placed in a place without vibration.
b) Input voltage check: The input voltage indicated by the adapter should be consistent with the power supply voltage, otherwise it will be
cause serious damage to the microscope.
c) Eyepiece: Insert the eyepiece into the eyepiece brief.
d) Objective lens: lower the stage to the lowest limit, and then screw the objective lenses of various magnifications into the object in turn
mirror converter and tighten.
e) Condenser: The condenser is already installed when the product leaves the factory.
f) Concentrator: The concentrator has been installed and positioned at the time, the concentrator is screw-mounted, and can be rotated counterclockwise.
out to remove.
g) Color filter: When a color filter is required, place the color filter on the variable aperture bracket under the condenser.
Operate
1. Insert the eyepiece into the eyepiece, and screw the objective lens into the converter according to the order of different magnifications. When observing, place the specimen in the center of the stage, clamp it with the glass claws, first use the low-power objective to find the image of the observed object, move the observed object to the center of the field of view, and then gradually transfer to the high-power objective. Observation, and at the same time use the micro-hand wheel for fine focusing until the object image is clear. When using the 100X oil immersion objective, it is necessary to fill the space between the front of the objective lens and the specimen plane with fir oil, and there should be no air bubbles in the oil droplets. After the oil lens is used, it should be wiped off with a small amount of xylene immediately to prevent the fir oil from solidifying over time. Not easy to remove.
2. In order to obtain a bright and clear object image during observation, attention must be paid to the adjustment of the illumination system. When using objective lenses with different magnifications, the condenser lens should be adjusted and the aperture aperture should be changed to make the numerical aperture suitable for the objective lens. Generally, In other words, when the magnification of the objective lens increases, the condenser must move upward, and the aperture diaphragm is designed for adjusting the numerical aperture, not for adjusting the brightness. Typically, the aperture aperture is opened to 70-80% of the objective's exit pupil until a clear object can be seen in the field of view.
3. When a large number of specimens of the same type are to be viewed, the limit screw can be adjusted to the appropriate position.
And lock it with a nut, so that after replacing the specimen, directly adjust the coarse handwheel until the first specimen can be seen.
To the position of a clear image, it can simplify the operation and reduce the work intensity.
Note: Specimens of the same type refer to sections, coverslips, and slides with the same thickness.
Product feature and application
The digital usb microscope can be used in medical and health institutions, universities, secondary schools, technical schools and other units for biological.
It is used for bacteriological observation, teaching and professional research, clinical experiment and routine medical examination.
This product has a novel shape and adopts a variety of advanced structures and technologies to make the instrument easy to use, safe and reliable.
Maintenance and precautions
1. Be careful when unpacking to prevent the lens and other accessories from falling and being damaged.
2. All lenses have been calibrated and adjusted, please do not disassemble them by yourself.
3. The objective lens changer and the coarse and fine focus adjustment mechanism have a compact structure, please do not disassemble it easily.
4. The instrument should be kept clean, the dust should be removed frequently, and the sliding parts should be regularly coated with a small amount of non-corrosive.
Corrosive grease, special care should be taken not to contaminate the optics when cleaning.
5. The instrument should be placed in a cool, dry place, and must be covered with a dust cover after use.
