Encoder Integration Enhances Design
To operate the system, the researcher would focus the microscope on an area if interest and hit the “Start” button. The CFocus system with its Mercury 3500 encoder would then provide automatic correction for thermal expansion and contraction.
“The Mercury encoder is easy to integrate because it is a kit encoder with the scale and sensor as separate, individually mounted components,” Mackay added. “The Mercury encoder was also the easiest to set up. It provides the broadest alignment tolerances, a ±2 degree sweet spot in the Theta Z-axis which is three times better than competing technologies. Plus, programmable interpolation integer steps, programmable output frequency, and automatic gain and phase correction circuitry make it very easy to optimize system performance.”
