How to adapt the stereomicroscope magnification observation to different requirements
Body microscopes are used for three-dimensional inspection and observation of electronic parts\integrated circuit boards\turn-head tools\magnets etc. Based on the fact that these different objects under test need to be observed at different magnification states, how to adapt to these different requirements? It can be solved in several ways a. By optical performance b. By video observation c. By mechanical performance d. By light source illumination
Optical performance: according to the object to be observed by the observation requirements, through the selection of different eyepieces \ objective lenses to solve the problem of large magnification and large field of view. Only require large magnification, can be replaced by large magnification eyepieces and objective lenses, require to see a large field of view can be replaced by the objective lens, reduce the eyepieces to meet the requirements.
Video observation: When optical magnification is not enough, electronic magnification can be used to compensate. When observing at the same time and wishing to be able to store and retain, we can choose video. There are various ways of video: A. directly through the monitor B. can be connected to a computer (through a digital CCD or analogue CCD image acquisition card) C. can be connected to a digital camera (different digital cameras should take into account the different interfaces and the compatibility with the microscope).
Mechanical performance: encounter some welding, assembly, larger integrated circuit board inspection field and the working distance requirements, we can through the mechanical performance to solve, such as universal bracket, rocking arm bracket, large mobile platform. With their performance characteristics, when the inspection of large objects directly through the bracket and platform can complete our inspection work. There is no need to move our object to be tested. For example: ABB company due to the inspection circuit board is relatively large and need to observe the subtle tilt, the circuit board is very difficult to move, only through the mechanical movement to complete the inspection work. The function of universal support can meet these requirements at the same time.
Light source lighting: light source lighting on the ability to see the object under test plays a crucial role, when choosing the lighting must be based on the characteristics of the object under test itself (taking into account its light requirements, strong \ weak \ reflective, etc.) to choose the appropriate lighting tools and lighting methods.
