How to adjust the viewing magnification of the stereomicroscope to suit different requirements
A stereomicroscope is used for three-dimensional inspection and observation of electronic components, integrated circuit boards, rotary cutting tools, magnets, etc. How to adapt to these different requirements based on the fact that these different objects need to be observed at different magnifications? It can be solved through multiple aspects. a. It can be achieved through optical performance. b. It can be selected for video observation. c. It can be achieved through mechanical performance. d. It can be illuminated by a light source
Optical performance: Based on the observation requirements of the measured object, different eyepieces/objectives are selected to solve problems such as high magnification and large field of view. When only high magnification is required, the high magnification eyepiece and objective lens can be replaced. When a large field of view is required, the objective lens can be replaced to reduce the eyepiece lens to meet the requirements.
Video observation: When the optical magnification is insufficient, electronic magnification can be used as compensation. When observing and wanting to store and preserve simultaneously, we can choose videos. There are various video formats: A. It can be directly accessed through a monitor B. It can be connected to a computer (via a digital CCD or analog CCD image acquisition card) C. It can be connected to a digital camera (different digital cameras need to consider different interfaces and compatibility with the microscope)
Mechanical performance: When encountering welding, assembly, inspection of large integrated circuit boards, and requirements for working distance, we can solve them through mechanical performance, such as universal brackets, rocker arm brackets, large mobile platforms, etc. With their performance characteristics, we can directly complete our detection work by using brackets and platforms when detecting large objects. No need to move our tested object. For example, due to the large size of the tested circuit board and the need for slight tilting observation, it is difficult for ABB to move the circuit board, and the testing work can only be completed through mechanical movement. The function of the universal bracket can simultaneously meet these usage requirements.
Light source illumination: Light source illumination plays a crucial role in whether the measured object can be seen clearly. When selecting illumination, it is necessary to choose the corresponding lighting tool and lighting method based on the characteristics of the measured object itself (considering its requirements for light, such as strong/weak/reflective, etc.).
