Stereo microscope use method Stereo microscope use environment
Stereo microscope, also known as "solid microscope" or "dissecting microscope", can produce an upright three-dimensional spatial image when observing objects. Strong sense of three-dimensional, clear and wide image, and has a long working distance, and is a very wide range of conventional microscope. Easy to operate, intuitive, high efficiency, applicable to the electronic industry production line inspection, printed circuit board verification, printed circuit components in the welding defects (printing misalignment, collapse edge, etc.) verification, single-board PC verification, vacuum fluorescent display VFD verification, etc., with the measurement software can be measured in a variety of data.
Usage
(1)After installing the microscope, make sure the power supply voltage is the same as the rated voltage of the microscope before plugging in the power plug, turning on the power switch and selecting the lighting mode.
(2) According to the specimens observed, select a good stage plate (observation of transparent specimens, the choice of hairy glass stage; observation of opaque specimens, the choice of black and white stage), loaded into the base of the stage plate holes, and lock.
(3) loosen the focusing slide on the fastening screws, adjust the height of the mirror body, visual working distance of about 80mm, (so that its magnification with the selected objective lens is generally consistent with the working distance) adjusted, locking bracket, will be the safety ring against the focusing bracket and locking.
(4) mount the eyepiece, first loosen the screw on the eyepiece barrel, mount the eyepiece and then tighten this screw (eyepiece into the eyepiece barrel, be especially careful not to touch the lens lens surface by hand);.
(5) adjust the pupil distance, when the user through the two eyepieces to observe the field of view is not a circular field of view, should trigger the two prism boxes, change the eyepiece tube pupil distance, so that it can achieve the observation of a completely overlapping circular field of view (indicating that the pupil distance has been adjusted);; (6) Observe the eyepieces, and then tighten this screw (when the eyepieces are put into the eyepiece tube, be especially careful not to touch the surface of the lens lens).
(6) Observe the specimen (focusing on the specimen). First of all, the left eyepiece barrel on the optic circle adjusted to the 0 mark position. Usually, the first from the right eyepiece barrel (i.e., fixed eyepiece barrel) in the observation, the zoom cylinder (with a zoom device model) to the highest times the position, turn the focusing handwheel to focus on the specimen until the specimen's image is clear, and then the zoom cylinder to the lowest times the position, at this time, with the left eyepiece barrel to observe, such as not clear, then along the axial adjustment of the eyepiece barrel on the degree of vision circle until the specimen's image is clear, and then again bimanual observation of its focusing effect.
(7) At the end of the observation, switch off the power, remove the specimen, and cover the microscope tightly with a dust cover.
Use of the environment
(1) The instrument should be avoided from direct sunlight, high temperature, humidity, dust and corrosion of acid and alkali gases.
(2) The working room should be kept clean, and the dust cover should be put on after the instrument is used; (3) The microscope should be kept clean and the dust cover should be put on after the instrument is used.
(3) The microscope should be placed on a firm and stable worktable.
(4)Avoid dirt or finger staining the lens and colour filter during operation.
Features
1. The left and right beams in the binocular tube are not parallel, but have a certain angle - body angle (generally 12 degrees - 15 degrees), so the image has a three-dimensional sense of three-dimensional;.
2. like upright, easy to operate and dissect, this is due to the prism below the eyepiece to invert the cause of the image;.
3. Although the magnification is not as good as conventional microscope, but its working distance is very long.
4. The depth of focus is large, so it is easy to observe the whole layer of the object being examined.
5. The diameter of the field of view is large.
