Fotonic Edge Probe
Measure Dynamic Edge
Position, Displacement,
Vibration or Runout at Speeds
up to 150 kHz
The MTI-2000 Fotonic Edge Probe
provides precise, accurate and
repeatable measurements of
displacement, runout and vibration of
thin objects. The unique probe design is
unaffected by target reflectivity or
shape, making it ideal for wide variety
of applications such as computer disk
drive runout, magnetic tape motion or
ultrasonic tool vibration. The ultra-low
noise characteristic of the Fotonic Edge
Probe produces static and dynamic
measurements with resolutions to 0.05
uin (1.25 nm).
The MTI-2000 provides outputs of
peak-to-peak vibration and displacement
via the digital display, analog dc voltage
output or RS-232 computer interface.
The dual channel design allows two
probes to simultaneously measure
displacements and vibrations at different
target locations.
Along with its high sensitivity, the
Fotonic Edge Probe is easier to set up
and use than other techniques. It only
takes a minute to position the probe
and obtain accurate, high-resolution
measurements. Custom designs are
available to adapt to almost any
application or space requirement.
