Features & Functionality
For the 885 range of cameras, the Global Clear functionality is used to keep the image area free of charge prior to the
external trigger pulse. This reduces the pre-trigger image smear which might be seen on other frame transfer sensors.
Also, due to the ‘iCam’ functionality of the 885, this feature can be used to allow the overlap of exposure and readout
but still maintain a charge free sensor prior to the external trigger pulse, see gure 34 below:
