1、 Usage and characteristics:
This microscope can be widely used for research in biology, bacteriology, histology, medicinal chemistry, etc. It can also be used for clinical trials in healthcare and for teaching purposes in school laboratories.
The instrument adopts an adjustable Abbe focusing lens group, which allows for a wider range of focusing light adjustment. The planetary coaxial coarse and fine adjustment focusing device ensures both comfortable and smooth focusing, as well as fine adjustment; A double-layer mechanical mobile platform with a reading scale, and its coaxial longitudinal and transverse adjustment handwheels make operation easier.
