Newports 845 digital shutter controller provides precise on/off control for durations from
10 msec–990 sec. A timed exposure can be initiated either from the front panel, through
TTL compatible signals, or from the pushbutton cable. In the MANUAL mode, the shutter
can be set opened to facilitate alignment or focusing. The RESET command, required
before each actuation, prevents accidental opening and closes the shutter even during a
timed opening. A 10 sec shutter opening delay can be activated as a convenience in
holography, and other applications, when vibrations must die down before exposure.
