Camera Range

Set the camera Range.
The narrower you set the camera range, the shorter the imaging time and the sampling period become.
The default value is the entire camera range. (Sampling period: 5 ms)
Purpose of narrowing the camera range
z z
Narrowing the camera range has advantages such as those shown below.
(a) Shortening of the measurement time
When you narrow the camera range, the sampling period will be shortened by a corresponding amount.
This makes it possible to perform measurements on production lines that move at faster speeds.
(b) Noise prevention
Depending on the workpiece profile and the environment, measurements may be unstable due to the
presence of noise and diffuse-reflected light.
Setting the camera area just to the measurement range can prevent the influence of these elements on
the measured results.
