primer on microscopes by Olympus Details This website is sponsored by Olympus company. It is similar to two other sites (one by Florida State University, the other by Nikon) already in asdlib whereby a common group of authors contributed to the development of all three sites. Thus, these sites are similar in content although differences exist. This Olympus site has a "virtual microscopy" that contains links to interacdtive tutorials that demonstrate the operation of different types of microscopes. Thus, one can compare how various types of microscopes work, play with controls, see how some settings can cause errors, etc. Optical microscopy per se is underutilized in the teaching of chemistry but is very important industrially. The site's applets and the way they are connected work well - a virtual lab that can be used effectively for instruction and learning. Currently 0.00/5 1 2 3 4 5 Rating: 0.0/5 (0 votes cast)
