Three research projects are a large platform mounted microscope: DMM-800C (infinity optical design) 

 First, the main uses and characteristics of the instrument 
 DMM-800 series of research by a large platform infinity optical microscope design with a large range of movement of the loading platform, Vertical illumination devices, flat-field achromatic objectives, wide field eyepiece, image clarity, contrast is good, both with a dark field and polarizing devices, metal, mineralogy, precision engineering, electronics and other research the ideal instrument. For schools, research, factories and other departments. 
 DMM-800C three research projects are set to a large platform is the elite microscope optical microscopy, advanced optical conversion technology, cutting-edge computer imaging technology combines the successfully developed a high-tech products. Can observe the microstructure of artificial images on a computer and can easily observe the metallographic images timely and capturing at any time, thus the analysis of microstructure profiles, ratings, etc., you can also save or print high resolution metallographic photos .

 Trinocular head tube shaft type, inclined 30 degrees, including the inspection polarizer 
 The main instrument of fine, coarse hand wheel, fine-tuning cell is 0.002MM (base and frame) 
 Polarized dark field device can plug-in polarizer, vertical lighting device, capable of general metallographic analysis, particle analysis and testing, but also the analysis of opaque objects, observation, and according to the light path in reflection, bright field, dark field and polarizer can be changed quickly. 
 The stage loading plate of glass, size: 274 X274mm a fast-moving device, moving the range size: 200 X 200mm 
 Coaxial coarse focus institution focusing mechanism, focusing range 15mm micro cell value 2μm 
 Vertical illumination lighting system 12V/50W, halogen lamp, adjustable brightness 
 Filter set blue, yellow, green, matte, neutral filter 
 Converter within the positioning within the curved ball, five-hole conversion 



 Third, the instruments of the main decomposition 
 DMM-800 is equipped with a refractive prism binocular tube compensation. Can adjust the left and right eyepiece diopter. This design allows the regulation of IPD, the objective remains the same focal plane of Qi, even if the switch to a different ratio of the lens, but also just to do the least amount of focus. Made by a rubber eyepiece ring to a more comfortable viewing. High-quality converters with internal five-hole mechanical positioning. This design makes the rotation more smooth, and increased the durability. At the same time, the converter with a sudden shocked weekly cycle, making the rotation even more convenient, without touch lens. 
 Five-hole converter binocular tube 

 X, Y axis parallel to the move, X-axis 200mm, Y Axis 200mm, designed to ensure the accuracy of the translation levels observed movement patterns, moving accuracy of 0.1mm. 

 Loading platform to mobilize the hand wheel 
 Coaxial coarse and fine focusing hand wheel position behind the bottom of the loading platform, and he and the loading position of the handle near the mobile, so operators do not need to twist the shoulders, can maintain a natural position to operate. Multi trinocular head design, making Trinocular color camera device can then also be connected digital cameras, traditional and also the human eye can observe the computer or digital camera to take pictures. 

 Coaxial coarse and fine focusing hand wheel Trinocular 
 This firmly installed on the host machine on the stage is built-in double-body, smooth in the XY direction of movement. Because of this institution is built-in design, not added, not added, so X will not be highlighted to guide the stage table, this design increases the space on the stage side, the operation becomes more convenient for specimens , fast, while the stage moves in the X-axis and more smooth and sophisticated. Smooth surface of the stage, so that the slide can be more smooth, comfortable movement.
