Nothing lights up a science classroom like a digital microscope that can enlarge a spider or human hair on a classroom projector, but these devices have been hard to work and expensive. Califone’s USB Digital Microscope
costs only $187, magnifies micro worlds 200-times and has automatic controls for brightness and color so whether you’re displaying video or still images, everything looks perfect. I really like the microscope’s filters that let the teacher choose among color, black and white, reverse image and three color filters. It’s small, comes with a stand and works with recent Windows releases as well as a variety of resolutions.
