A brief introduction The ZJ-300 universal fixed large stand stereo microscope has a wide range of movement and can produce an upright three-dimensional spatial image when observing objects. The imaging has a strong and clear three-dimensional sense, a wide field of view, and a long working distance. Continuous magnification can be achieved for viewing the same object, and different lighting sources can be selected according to the different observed samples. Detailed introduction of ZJ-300 universal fixed type 1. Stereoscopic microscope with large bracket ZJ-300/400ZJ-300 universal fixed type 2. Large stand stereoscopic microscope three-dimensional mobile fixed stand ZJ-300 3. The ZJ-300 universal fixed large stand stereo microscope has a wide range of movement and can produce an upright three-dimensional spatial image when observing objects. The imaging has a strong and clear three-dimensional sense, and a wide field of view Long working distance. Continuous magnification can be achieved for viewing the same object, and different lighting sources can be selected according to the different observed samples. 4. The instrument has high resolution and a wide field of view clarity, which can be used not only for teaching demonstrations and observation and analysis of biological anatomy, but also for the electronic industry and precision machinery 1、 Technical parameters of ZJ-300 large stand stereo microscope: 1.
