The trinocular compound siedentopf LED microscope provides phase contrast microscope system and brightfield microscope system. The phase contrast microscope comes with LED illumination with variable intensity, Abbe NA1.25 condenser with iris diaphragm and a complete set of phase contrast kit. The compound microscope features an optical system for observing images through eyepieces and an adjustable trinocular port. It offers eight levels of brightfield magnification from 40X to 2000X. The phase contrast microscope can improve the images of transparent and colorless objects, which are hard to see or invisible in an ordinary microscope. This phase contrast compound microscopy is widely used clinical, biological, research and schools, specially for observing live cells.
