XJL-101/201 Series upright metallurgical microscopes are suitable to observe surfaces of opaque object or transparent object. They are equipped with Kohler illumination and excellent logne working distance plan achromatic objectives and wide field eyepieces, provited excellent optical quilatity and operation performance. The main frame body is designed “T” type to content the shock resistance and big smaple cheching. The big size moving stage can be moved slow-motion or double-quick, and enable selection mode of the lift motion device, such as stage or objectives unit lift motion, so that content the different thickness sample. They have beautiful sculpt and convenient operation. They are the ideal instruments in research work for metallography, mineralogy, precision engineering, electronics, etc.
