You can easily switch between these orientations by rotating the camera 90° and

changing the binning parameters in the application software.

Exposure - Readout Modes

The frame transfer CCDs used by the PhotonMAX support Overlap and Non-Overlap

exposure - readout modes. If you are planning to use Overlap mode, be aware that the set

exposure time ( Experiment Setup|Main tab page) may not be the effective exposure

time: the frame readout time is the determining factor in this mode.

Overlap Mode (Simultaneous Exposure-Readout)

Overlap mode is extremely useful in applications requiring continuous imaging (100%

duty cycle). Once a frame is exposed and transferred into the frame transfer area, the next

exposure immediately starts and continues until the previous frame is read out of the

frame transfer area or until the exposure time is finished, whichever is longer (so the

minimum effective exposure time in this mode is the readout time). This mode of

operation allows you to continuously image a specimen to obtain better kinetic

information about a process.

In WinView and WinSpec, this sequence is programmed by simply setting:

Figure 33 shows the required selections for overlap mode.
