The SmartShutter® raises the bar for shutter performance and dependability and is created to go along with expanding array of optical solutions by Sutter. There are two or more "leaves" that rub against one another in the conventional shutter design. The blades will eventually degrade, bind, and stop moving, making the shutter impossible to open. As there is only one moving component in the SmartShutter, wear is nearly eliminated, and performance is significantly enhanced. The leaves of the classic shutter design can also become bound in extreme temperatures. The shutter's lifespan is increased by Sutter's improved design, which makes use of heat-resistant material that functions effectively in extremely hot settings.

To increase control and reliability, the SmartShutter features a new high-performance motor drive and precise stepper-motor. The solenoid actuator used in conventional shutters needs a high initial opening voltage in order to open the shutter quickly. If the shutter is opened too frequently, this could cause the coil to overheat or burn out. You may regulate the trajectory of each move and adjust the motion of the blade for speed or for smoothness with a microprocessor controlled motor/wiper design. The SmartShutter functions with open/close times of 8msec from the command in either the 25 mm or 35 mm version (3msec from the start of motion). It is possible to achieve continuous operation at specific frequencies up to 40 Hz for the 25 mm version and 20 Hz for the 35 mm variant because to Sutter's robust design, which does not rely on over-driving the windings. Although the 25 mm SmartShutter® can operate between 30 and 40 Hz, resonances may be excited at certain of those frequencies, which will impede reliable operation. Usually, this can be fixed with a little frequency change.

SmartShutter® systems evaluated for over 100 million cycles show no indication of failure since the shutter blade is stopped by the motor's action instead of by mechanical stops. Aluminium that has not been treated makes up the conventional SmartShutter blade. On request, non-reflective coatings are available, but they shouldn't be used with arc lamps.

The microprocessor-based controller has excellent adaptability and may be configured to perform in a variety of ways. By choosing the degree of shutter opening, the SmartShutter® may be set to provide a variable aperture or a range of movement profiles. The shutter functions as a programmable neutral density filter when paired with a liquid light guide in Lambda LS xenon light source. Also, although the shutter has a little impulse, a "soft" action option can be chosen to lessen vibration.

Up to two shutters can be driven by the SmartShutter®'s Lambda 10-B/IQ controller. A TTL input is provided to facilitate remote triggering of the shutter, and a TTL output is provided to support remote triggering of external devices like a camera. Moreover, the controller can be controlled manually locally via the keypad or remotely from a computer using either the USB or serial interface.

The Lambda SC, a specialized single shutter controller, is additionally offered. This device comes with a serial port, USB port, TTL in port, and TTL out port. With the Lambda SC, the exposure period and the interval between trigger and shutter opening can both be programmed.

Housings are offered for use with our Lambda LS and Lambda DG-4/DG-5 optical devices, as well as stand-alone units. They were originally created to be fitted into our 25 mm and 35 mm filter wheels. The SmartShutter®'s modular design ensures that repairs, should they be required, will be quick and affordable.
