The ZDot™ technology also simplifies operation and setup, by projecting a focusing onto the samples top and bottom surfaces. When the top or bottom surface is correctly focused, the ZDot™ grid will appear in the highest contract, making it fast and intuitive to correctly set up samples. The Zeta-388 is easy to operate, even for less experienced users.
