The trinocular compound siedentopf LED microscope provides phase contrast microscope system & brightfield microscope system and a super speed 18MP USB 3.0 imaging digital system. The phase contrast microscope comes with LED illumination with variable intensity, Abbe NA1.25 condenser with iris diaphragm, 18MP USB 3.0 camera 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 six levels of brightfield magnification from 40X to 2500X. The phase contrast microscope can improve the images of transparent and colorless objects, which are hard to see or invisible in an ordinary microscope. The 4912x3684 pixels USB 3.0 digital imaging system that captures still microscope images and live video on computer. The included software is compatible with Windows, Mac OS X and Linux operating systems (see version information below). The Windows software can also be used to make measurements. This phase contrast compound microscopy is widely used clinical, biological, research and schools, specially for observing live cells.
