Microscope Performance and Accessories Te choice of microscope also depends on the subject mat-

ter and level of the course. In many cases appropriate accesso- ries are needed to perform certain experiments. Microscopes can be equipped to match the requirements of the subject under study. Accessories. Some accessories depend on the applica-

tion, for example polarization kits are important for the study of minerals in geology classes. Other accessories can be gen- erally beneficial, for example LED illumination, which lasts much longer than halogen bulbs. Te long lifetime of LED lighting eliminates bulb changes and increases microscope uptime. Digital cameras and associated soſtware have become more important in the past few years, as microscopy itself has become more digital. Some cameras can even create their own Wi-Fi hotspot so that students can access images with their mobile devices or laptops (Figures 3). Course level. Microscopes for biology classes in high

school do not need the same capabilities as microscopes for advanced university pathology courses. Tere are different types of student microscope that can usually match the needs of students (Figure 4) [1]. Budget. Te price-performance ratio always requires care-

ful consideration. In the years we have spent talking to teachers, we have learned that nothing is more frustrating for students than lousy images that don’t mean anything. For a teacher, nothing is more rewarding than seeing students excited about what they see in the microscope. Terefore, our advice is the following: never compromise on the optical performance. Only great images delight young minds.

Summary Answers to the following questions will help you select the microscope that best fits your needs:

1. Where will the microscopes be used and stored? Will they be moved oſten?

2. How sturdy are the instruments? Will they stand up to daily use? Do the moveable parts move easily for a good user experience?

3. How easily can the microscopes be operated? Will students see something fascinating quickly? Tis effect should not be underestimated: the easier great images can be seen, the more fun the students will have.

4. For which lessons will the microscope be used? Is any special equipment needed? Which equipment will not be needed?
