SmartShutter?® Controller Sutter Lambda SC

The Lambda SC is a full-featured microprocessor-controlled SmartShutter® shutter driver. It delivers improved performance through extra modes of operation and implements the same shutter command set as other Sutter's Lambda controllers. The extra operating modes provide you programmable control over the shutter opening and triggering mechanisms, exposure time, number of exposures, and delay between exposures. Via serial or USB connections, the Lambda SC utility program enables computer control and configuration of several SC controllers.

Shutter timing is directly influenced by command occurrence times or TTL input in the Lambda 10 family of filter wheel controllers. Most often, the system software associated with these controllers offers options for altering the shutter timing. Applications that would profit from improved control options incorporated within the controller may use the Lambda SC shutter controller. On the front panel, there is a handy toggle switch with three settings: Open (which causes the shutter to open independently of other inputs), Closed (which causes the shutter to close independently of other inputs), and Auto. The controller can be opened and closed while in the Auto position using a logic level input or remotely from a computer through a USB interface.

The shutter will constantly open and close in free running mode. Either the interval for the complete cycle or the time between closing and opening can be directly timed. The user can configure delay and exposure intervals with millisecond resolution for up to 5 hours. This mode can be configured to continue indefinitely or to loop for a predetermined number of cycles. The mode is started by a trigger pulse or power-up, and it can be stopped by issuing a stop command.

The SmartShutter®'s motor/wiper design is computer controlled, allowing for precise control of each movement and smooth or rapid optimization of the blade action. The user can choose the fast option when speed is the most crucial factor. The "soft" mode, which moves the blade more slowly through the total travel, can be chosen if the rapid mode's slight vibration is undesirable and speed is not crucial.

The SmartShutter® partially opens when in neutral density mode. You can choose from any of the 144 steps between fully closed and fully open. By spatially homogenizing the light and using a liquid light guide in conjunction with this variable aperture opening, it is possible to create a consistent spatial illumination that is unaffected by the geometry of the input illumination.

Most microscope illumination connections can be connected to the SmartShutter using an adapter, which is a separate item. For more details, please see the Microscope Adapters page. To get rid of reflection, the shutter blade might be coated with optical black. Call Sutter for more information.
