Photovoltaic panel inspection microscope can observe dislocations, scratches, broken edges, etc. that are difficult to observe with the naked eye; it can also analyze the impurities and residue components of silicon wafers. Impurities include: particles, organic impurities, inorganic impurities, metal ions, silicon powder dust, etc., which cause the silicon wafers after grinding to be prone to change, blue, black, etc., making the grinding unqualified. It is one of the indispensable inspection instruments in the production process of solar cell silicon wafers. CGM-600E large platform bright and dark field silicon wafer inspection microscope is suitable for microscopic observation of solar cell silicon wafers. This instrument is equipped with a stage with a large moving range, an epi-illuminator, a long working distance flat-field achromatic objective lens, and a large field of view eyepiece. The image is clear and the contrast is good. It is also equipped with a polarizing device and a high-pixel digital camera. This instrument is equipped with a dark field objective lens, which makes the image clearer when observing silicon wafers. It is an ideal instrument for detecting the microscopic morphology distribution of the "pyramid" of solar cell silicon wafers and defect analysis of silicon wafers.

3. Photovoltaic panel inspection microscope instrument main body decomposition The DMM-800 is equipped with a prismatic binocular tube with diopter compensation. The diopter of the left and right eyepieces can be adjusted. This design allows the objective lens to remain in focus when the pupil distance is adjusted, and only a minimum amount of focusing is required even when changing objectives of different magnifications. The eyepiece ring is made of rubber for more comfortable observation. The high-quality five-hole converter has a mechanical stop inside. This design makes rotation smoother and enhances durability. At the same time, the converter has a ridge around the ring, which makes rotation easier without touching the objective lens. Binocular tube Quintuple converter
X and Y axis parallel movement, X axis 200mm, Y axis 200mm, high-precision translation design ensures horizontal movement of the observation sample, and the movement accuracy is 0.1mm.
Stage adjustment hand wheel The coaxial coarse and fine focusing hand wheel is located at the lower back of the stage, and it is close to the stage moving handle, so the operator does not need to twist his shoulders and can maintain a natural posture to operate. The multifunctional trinocular head design allows the trinocular head to be connected to both a color camera and a digital camera, allowing traditional human eye observation as well as computer observation or digital camera photography.
Coaxial coarse and fine focusing hand wheel Trinocular head This mechanical stage, firmly mounted on the mainframe, is a built-in double-layer mechanism that allows smooth movement in the XY direction. Because this mechanism is built-in, rather than attached, the X-guide rail does not protrude from the stage surface, which increases the space above the stage, making specimen manipulation more convenient and quick, while also making the stage move more smoothly and precisely in the X-axis. The smooth surface of the stage allows the slide to move more smoothly and freely.
