Stereomicroscope use environment
Stereo microscope, also known as "solid microscope" or "dissecting mirror", can produce upright three-dimensional spatial images when observing objects. It is a conventional microscope with strong stereoscopic impression, clear and wide imaging and long working distance, and it is widely used. The operation is convenient and intuitive, and the verification efficiency is high. It is suitable for the inspection of electronic industry production lines, printed circuit boards, welding defects (printing misplacement, edge collapse, etc.) in printed circuit components, single-board PC, vacuum fluorescent display VFD, etc., and can measure various data with measurement software.
method of application
(1) After installing the microscope, plug in the power plug, turn on the power switch and select the lighting mode after ensuring that the power supply voltage is consistent with the rated voltage of the microscope;
(2) according to the observed specimens, choose a good bedplate (when observing transparent specimens, choose ground glass bedplate; Observe the opaque specimen, choose black and white bedplate), put it into the bedplate hole of the base, and lock it;
(3) Loosen the fastening screw on the focusing slide seat, adjust the height of the mirror body, and visually observe that the working distance is about 80mm (the working distance is roughly the same as the magnification of the selected objective lens). After adjustment, lock the bracket and lock the safety ring close to the focusing bracket.
(4) When installing the eyepiece, loosen the screw on the eyepiece barrel first, and then tighten the screw after installing the eyepiece (when putting the eyepiece into the eyepiece barrel, be especially careful not to touch the lens surface of the lens);
(5) Adjust the pupil distance. When the user observes the field of view through two eyepieces, it is not a circular field of view, and the two prism boxes should be pulled to change the pupil exit distance of the eyepiece barrel, so that a completely coincident circular field of view can be observed (indicating that the pupil distance has been adjusted);
(6) Observe the specimen (focus the specimen). First, adjust the visibility circle on the left eyepiece barrel to the 0-line marking position. Usually, first observe from the right eyepiece tube (fixed eyepiece tube), turn the zoom tube (when the zoom device model is used) to the highest magnification position, turn the focusing handwheel to focus the specimen until the image of the specimen is clear, and then turn the zoom tube to the lowest magnification position. At this time, observe with the left eyepiece tube. If it is unclear, adjust the visibility circle on the eyepiece tube along the axis until the image of the specimen is clear, and then observe its focusing effect with both eyes.
(7) At the end of observation, turn off the power supply, remove the specimen, and cover the microscope tightly with a dust cover.
operational environment
(1) The instrument shall be protected from direct sunlight, high temperature, humidity, dust and acid-base gas corrosion;
(2) The workshop should always be kept clean, and the instrument should be covered with dust cover after use;
(3) The microscope should be placed on a firm and stable workbench;
(4) Avoid soiling lenses and color filters with dirt or fingers during operation.
