The digital microscope is the innovation of microscope, it is broke through the functional highpoint of microscope and created a epoch in microscopy! Through redesigning the light path of microscope, establishing the CMOS sensors into the trinocular tube of microscope head, receiving the image through CMOS, then sent to the computer in the form of digital signal, and reproduced the image in real on the computer monitor. Digital technology applied in microscopes, brought the much wider application of the microscope. The specially developed image measurement software of digital microscope makes the image clear at a glance for the users. The displayed image on the computer monitor is increased hundred or thousand times than the image you see in the eyepiece, and this makes the observation of the specimens much clearer and more convenient.
