Shutters in this group are designed for high optical power and damage thresholds, but with lower emphasis on speed.

The Safety Interlock Shutter is normally kept open for long periods of time, closing only for breaches in the safety system or at the end of an experiment.

The Process Control Shutter is used at frequent intervals, allowing equipment to move or change in between optical exposures. An example would be laser cutting. At various points, the shutter would block the laser to allow table repositioning and cutting to resume.

All Safety Interlock and Process Control Shutters are failsafe and close upon power loss. They are not dependent on gravity to close.

Switching speed requirements for safety and process applications are moderate. The flexure technology used in these products offer inherent fast switching without developing large heat loads in the electromagnet.

Many of these applications can use low power, simple electronic drive systems. See our Application Notes page for more on OEM and user built drive circuits. Our Shutter Controllers product line offers the most convenient way to drive the shutter and extract all benefits of the shutter design.

Position sensors are on most of the models, providing a safety or process circuit with verification that the shutter did indeed open or close as it was instructed to do from the power circuit.
