Basic Operations
To use your ContourGT-K system you must become familiar with the processes of:
• Turning on and off the system and starting/stopping the Vision64 software.
• Positioning a sample for measurement:
1. Placing the region of interest within the field of view of the camera.
2. Adjusting the system focus so that fringes are visible on the sample surface.
3. Adjusting the relative tilt between the sample and the reference mirror to ensure that
fringes are visible.
• Selecting the measurement parameters and making a measurement.
These process are covered in general in this chapter. Chapter 3 demonstrates how to make basic
PSI and VSI measurements with this hardware and software. If you are already familiar with
optical-surface profilers you may wish to skip directly to Chapter 3.
2.1 Turning On the System & Starting the Vision64 Software
1. Turn on the system power.
All ContourGT-K systems are equipped with a single
DC power supply that must be turned on; the manual
ContourGT-K systems are equipped with a powersupply as
depicted in the top picture and the automated ContourGT-
K systems are equipped with the PDU power supply as de-
picted in the bottom picture. The On/Off switch is located
on the back of the powersupply box.
ContourGT-K systems with motorized axes are also
equipped with an EMO box. There is an additional Power
On button on the EMO box that must be pressed to de-
liver power to the system. (Note that if the Emergency Off
button is depressed, it must first be released.)
2. Turn on and log in to the computer.
