The HIROX Hiscope is a dedicated digital microscope, that is, there is no provision to observe the sample directly through the lens except with a digital camera. Once that design decision had been made the system was optimized for the characteristics of the imaging sensor - a flat, 2-D array with a known readout rate, response curve, pixel size, etc. In a conventional microscope the optics of the eye have to be figured into the design parameters and that requirement may be different from and potentially conflict with those that would produce optimal images with an electronic imaging sensor. Because the HiScope has been designed only for digital imaging no compromises have had to be made to accommodate the eye's optics. However, the system is, in fact, often able to take advantage of sight physiology and visual signal processing to provide unique observational capabilities, i.e. 3-D Rotational Microscopy.
