8.1.3. Exposure Time

On exposure of the sensor, the inclination of photons produces a charge separation on 
the semiconductors of the pixels. This results in a voltage difference, which is used for
signal extraction.
The signal strength is influenced by the incoming amount of photons. It can be increased 
by increasing the exposure time (t
On Baumer SXC cameras, the exposure time can be set within the following ranges (step
