Light emitting amount selection function
When sensing transparent objects and minute objects, the light emitting amount can be changed without changing the response time, even
for cases where the incident light intensity is fully saturated, which was not possible with conventional models. This allows stable sensing to
be maintained, and there is no longer any need to change the sensing range or change the fiber sensor as used to be required.
Example: Sensing glass substrate
Comparison of saturation remedies
Fibers are available which are ideal for glass substrate conveyor processes.
