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.
