Release Notes:

For AC4040BSI camera:

• Eliminates a noise bump in short exposures (0.35s to 0.8s) by optimizing the activation of the sensor's low dark current operation.
• Reduces dark current related noise by ~7% in full frame images, and proportionally more the smaller the subframe.
• Corrects a problem where long exposure images may have obviously corrupt data under rare circumstances
• Improves image consistency after long idle periods. The camera flushes the sensor periodically when it is inactive to prevents possible charge build up evident in the first image taken after a long idle period. This provides greater image consistency regardless of image cadence.

For both FSI and BSI cameras:

• The camera automatically closes the mechanical shutter on power-up. It will stay closed until actuated, that is, until a light frame is requested. This reduces dust falling on the chamber window.
• Minor corrections and performance improvements based on customer feedback.
• For all cameras, improved performance will require taking new calibration frames.
