1Characteristics and application directions of BM-44X.9F three eye dark field microscope
Microscope features:
The BM-44X.9F dark field biological microscope is mainly used to observe objects related to structural and refractive index changes, such as diatoms, radiolarians, bacteria, and other single-cell organisms with regular structures, as well as linear structures in cells such as flagella and fibers. Particles below the resolution limit of the objective lens can also be observed using a dark field biological microscope.
