Frequently Asked Questions
What resolution does the SMT-9700 achieve?
Nanometer to sub-nanometer resolution, depending on the sensor, configuration, and calibration. Its proprietary PWM (phase-detection) circuit gives an inherently low noise floor compared with amplitude-based systems.
What channel configurations are available?
1, 2, or 3 channels. With the 3-channel option, all channels run off the same frequency and tune together — reducing mounting costs and machine space.
What are typical SMT-9700 applications?
XYZ stage position feedback in atomic force microscopy, Z-axis feedback in semiconductor photolithography, spindle position in precision grinding of bearing races, and optics positioning.
