Laser Shutters

CVI Melles Griot (Rochester, NY) recently introduced SafeClose laser shutters, based on the proven rotor drive actuation technology modified to close on power down. The proprietary Rotor Drive actuator provides a reliable, multimillion- cycle operation and ability to withstand harsh environmental conditions, including wide temperature variations (from -40°C to +70°C), high shock, and vibration in a clean environment. Designed for laser safety and laser switching, the SafeClose shutter was designed to be highly reliable and to always maintain laser safe conditions by closing automatically when power is interrupted. The fail-safe magnetic return mechanism guarantees that the blade will reliably close upon signal interruption. The SafeClose shutter does not require a separate controller and a simple 9V DC signal is sufficient to actuate the shutter and hold it open.
