Your application is the most important factor in choosing a microscope. What you need to see and what you want to do with that image will determine what kind of microscope you need. Microscopes typically come in two types: compound or stereo microscope.
A compound microscope has two or more lenses for greater magnification - the better to see small objects. The compound is about better viewing aided with technical add-ons.You can request for assembled microscopes if you want cheaper units. The assembled parts are sourced from different microscope brands to give you a hybrid that works just as efficiently.
