Stereo Microscope Easy To Operate, Intuitive, High Verification Efficiency
Edit: Ningbo Yaki Optical Instrument Co.,Ltd    Date: Oct 24, 2017

A stereo microscope is often referred to as the main force in a laboratory or production department. What are the factors to consider when choosing a stereo microscope? The answer is: "Look at the situation." Why is that? Because it depends on the use, depending on the task the user wants to accomplish. A stereo microscope is basically a tool to magnify a three-dimensional target in three dimensions. Unlike a duplex microscope, a stereo microscope can cope with this task.

In the stereoscopic microscope and other optical instruments, the chromatic aberration is a kind of distortion, the lens cannot concentrate all colors to the same convergent point. This is because the lens has a different refractive index (dispersion of the lens) for different wavelengths of light. The refractive index decreases with the increase of wavelength. The purpose of good optical design is to reduce or completely eliminate this effect.

Achromatic lenses are lenses designed to limit the effects of chromatic aberration and spherical aberration. After correcting the achromatic lens, the two wavelengths (usually red and blue) are focused on the same plane. Such lenses or microscopes are used in the following tasks, i.e. no color reproduction and mainly evaluation of geometrical properties. On the other hand, the achromatic lens is designed to focus on the same plane at three wavelengths (red, green and blue). Working distance

This is the distance between the lens and the top of the specimen when the specimen is focused. In most cases, the working distance of the objective lens decreases with increasing magnification. In a stereo microscope, working distance is one of the most important criteria because it directly affects the usability of the microscope as a tool.

In stereo microscopes, lighting is the key to exposing all work to light. The correct illumination will only be changed by changing the type of light, so that the desired structure is visualized, or the new information about the sample is discovered. It is important to correctly match the lighting to the right microscope and the right use.

The stereo microscope, also called "Solid microscope" or "Anatomy Mirror", can produce a positive three-dimensional space image when observing objects. The stereoscopic sense is strong, the image is clear and broad, also has the long working distance, and is the application scope very extensive common microscope. Easy to operate, intuitive, high efficiency, applicable to the electronics industry production line inspection, printed circuit board verification, printed circuit components appear in the welding defects (printing dislocation, collapse, etc.) of the verification, single Board PC verification, vacuum fluorescent display VFD verification and so on, with measurement software can measure a variety of data.

(1) After the microscope is installed, in order to ensure the supply voltage and the nominal voltage of the microscope can plug the Power plug, turn on the power switch, and select the lighting mode;

(2) According to the specimens observed, select a good table (to observe transparent specimens, the use of wool glass plate; Observe the opaque specimen, choose black and white board), load the base plate hole, and lock tightly;

(3) Loosen the fastening screws on the focusing slide, adjust the height of the mirror, visual work distance in the 80mm or so, (make it with the selected objective lens magnification of the general working distance) adjusted, locking bracket, the safety ring close to the Gioto frame and lock;

(4) Install the eyepiece, first to loosen the screws on the eyepiece tube, install the eyepiece and then tighten the screws (the eyepiece into the eyepiece tube, to be particularly careful, do not touch the lens lens surface);

(5) Adjust pupil spacing, when the user through two eyepiece observation field is not a circular field of view, should be flipped two prism box,Stereo Microscope change the eyepiece cylinder of the pupil distance, so that it can observe a fully coincident circular field (the pupil distance has been adjusted);

(6) Observation specimen (focusing on specimen). First, the visual circle on the left eyepiece tube is transferred to the 0-notch position. Normally, first from the right eyepiece tube (that is, the fixed eyepiece tube) to observe, the variable-fold cylinder (with the variable-times device model) to the highest position, rotation focusing handwheel on the specimen focus, until the image of the specimen is clear, and then turn the drum to the lowest position, at this time, with the Zootia tube observation, if not clear,Stereo Microscope along the axis to adjust the visual circle on the program Mirror tube , until the image of the specimen is clear, and then binocular observation of its focusing effect;

(7) At the end of the observation, turn off the power, remove the specimen and cover the microscope with a dust shield.
