Brightfield&Darkfield Biological Microscope BM200D+3.0MP USB Digital Camera Description: The External Digital camera darkfield biological microscope BM200D with 3.0MP USB digital Camera is made up of the BM200D(T) and professional high resolution 3.0MP digital camera with USB2.0 connection, The included 3.0mega pixel camera comes with basic measuring software that allows image capture and this kind of external digital microscope is more flexible compared to the build-in or integrating digital camera microscope. The external digital microscope lends greater flexibility - you can use different cameras on the same microscope and vice versa. And the digital camera could be added on other regular microscope too. And it is more convenient. Application: This darkfield and brightfield biological compound microscope is designed for clinical examination and teaching demonstration in medical field, veterinary offices, laboratories and colleges. It is a simple procedure which can be used on live transparent specimens, specimens which normally need to be stained (and therefore killed).you can use the dark field in the research of live bacterium, as well as mounted cells and tissues. It is more useful in examining external details, such as outlines, edges, grain boundaries and surface defects than internal structure. Features: 1. High resolution external 3.0MP digital camera with software and USB 2.0 ouput 2. perfect for observations of live ,transparent and unstained specimens. 3. Ideal tool for Clinics, Vets, Doctors and College Students 4. Professional darkfield condenser, and darkfield 100x lens with cone diaphgragm. 5. more useful in examining external details, such as outlines, edges, grain boundaries and surface defects 4. Professional darkfield condenser, and darkfield 100x lens with cone diaphgragm. 5. more useful in examining external details, such as outlines, edges, grain boundaries and surface defects 6.
