The Lambda SC is a full-featured microprocessor controlled shutter driver for the SmartShutter®. It supports the same shutter command set used for our other Lambda controllers and offers enhanced performance through additional modes of operation. The additional operating modes allow programmable control over the exposure time, the delay between exposures, the number of exposures, the mode of triggering, and the mode of shutter opening. The Lambda SC utility program allows computer control and configuration of multiple SC controllers through serial or USB ports.

In the Lambda 10 family of filter wheel controllers, shutter timing is controlled directly by the time of occurrence of commands or TTL input. In most cases, the system software used with these controllers has provisions for controlling the timing of the shutter. The Lambda SC shutter controller may be used in applications that would benefit from enhanced control options built into the controller. A convenient toggle switch on the front panel has three positions: Open (shutter will open regardless of other inputs), Closed (shutter will close regardless of other inputs) and Auto. In the Auto position, the controller can be operated remotely from a computer through the USB port, or opened and closed using a logic level input.

In the free running mode, the shutter will open and close repeatedly. The time between closing and reopening can either be directly timed, or set as an interval for the entire cycle. Delay and exposure intervals can be set by the user for up to 5 hours with millisecond resolution. This mode can be set to continuously run or loop for a specific number of cycles. The mode is initiated from power up, or a trigger pulse, and can be interrupted by using a stop command.

Because the SmartShutter® incorporates a microprocessor controlled motor/wiper design, the trajectory of each move can be controlled and the motion of the blade optimized for speed or for smoothness. When speed is the most important condition, the user can select the fast mode. If the modest amount of vibration in the fast mode is objectionable and speed is not important, the “soft” mode can be selected, moving the blade slower through the overall travel.

The neutral density mode results in a partial opening of the SmartShutter®. Any one of the 144 steps from a fully closed to fully open can be selected. Using this variable aperture opening along with a liquid light guide acts to spatially homogenize the light to produce a uniform spatial illumination that’s independent of the geometry of the input illumination.

The SmartShutter can be coupled to the illumination ports of most microscopes using an adapter which can be purchased separately. Please refer to the Microscope Adapters section for further information. An optical black coating option for the shutter blade is available to eliminate reflection. Please phone Sutter for details.
