Optical system：Infinity color corrected optical system（CSIS），better image，higher resolution, more comfortable observation;
Eyepiece and Objective：high eyepoint widely plan eyepiece PL10x/22mm provid e more widely and plan observation space and can be installed various of micro meter. Professional infinity plan achromatic LWD metallurgical objective, no cover glass design.
Viewing head：Gemel trinocular head diopter adjustable 45°inclined，can photo graph and image pickup，can collect and preserve the image, also can analysis the image with computer and specialized software.
Focus：Low hand position coaxial coarse and fine focusing mechanism，with coarse tension adjustment device，Coarse adjustment range 38mm，precision of fine adjustment 0.002mm.
Illuminator system：Reflection Koehler illuminator with iris diaphragm and center able filed diaphragm, wide voltage 90-240V ，12V/50W imported halogen bulb， effectively protect and extend the life of halogen bulb.
Stage：can be setting coaxial low hand position removable stage and the stage extension plate, expand the application space, to meet the different needs of cus tomers.
