One of the challenges in designing a confocal microscope is choosing the scan system configuration. The selection is based largely on the microscope application and involves a few distinct schemes. One scheme, moving mirror using galvanometer and resonant scanners, has been shown to offer an excellent solution exhibited by the large number of commercial systems which utilize them. Perceived shortcomings, such as slow image acquisition, are being dispelled due to the advent of large angle, high frequency resonant scanners. These newer devices offer near video rate performance at good scan efficiency.
