6.5.2 Exposure Times for the acA2000-165 and
acA2040-90
The section presents the minimum allowed and maximum possible parameter values for the
ExposureTime parameter (Table 34) for acA2000-165um/umNIR/uc and
acA2040-90um/umNIR/uc cameras. The other camera models are considered in Section 6.5.1.
The minimum allowed exposure times depend on the bit depth of the current pixel format and on
the currently available USB 3.0 bandwidth (see Table 34 and Figure 59).
6.5.3 Setting the Parameter Value
You can use the Basler pylon API to set the ExposureTime parameter value from within your
application software. The following code snippet illustrates using the API to set the parameter value:
// Set the exposure time to 3500 µs
camera.ExposureTime.SetValue(3500.0);
You can also use the Basler pylon Viewer application to easily set the parameter.
For more information about the pylon API and pylon Viewer, see Section 3.1 on page 61.
