full_question: One type of these devices can run in a constant height or constant current mode, and functions by creating a bias and measuring the tunneling current. These devices are used to locate hybridized probes in FISH ["fish"], and can identify locations stained with phalloidin derivatives or DAPI ["DAH-pee"]. One type of these devices uses dichroic mirrors to isolate specific wavelengths of fluorescence. Samples used in these devices may need to be mounted and placed under a coverslip. Anton van Leeuwenhoek's ["LAY-ven-hook"] use of these devices led to his observations of "animalcules" which were later revealed to be microbes. For 10 points, name this sort of device which uses a set of lenses to magnify an image.
