The model 76992 is our fastest shutter. It is especially suited to laser or focal plane use and applications including beam modulation at frequencies up to 150 Hz. The shortest pulse using the 76992 is shown with the aperture uniformly illuminated so the pulse rise and fall times include the large contribution from the outer zones.
The shutter driver
All Shutters can be triggered manually with the open/close switch on the driver, with an externally applied TTL gate signal or open/close signal, or via the RS232 interface. The trigger type is determined by the speed and accuracy required of the shutter system. TTL signals provide the most precise control since the shutter drive mimics the input pulse. To synchronize the shutter to other computer driven equipment, without concern for precise timing of the shutter transitions, the RS-232 interface is convenient. If the shutter is to remain open and closed for long periods of time and there is no need to drive the shutter from an external event, use the manual open/close switch.
The shutters have 1.5 Inch Series flanges and a 1/4-20 tapped hole in the bottom for rod mounting. An optical rod is not included.
Exposure times are determined by an external pulse source or switch contact closure.
When power is lost, the unit is powered down; when power is restored, the unit must be reset to resume operation.
When a break is detected in the external switch contact, the unit is powered down; when power is restored, the unit must be reset to resume operation.
All shutters include a fast synchronizing sensor activated by a vane attached to the shutter blade. The sensor sends out a TTL signal when the shutter is greater than 90% open. The signal is available at a BNC connector at the rear of the controller.
