Rotor Drive Shutters

Melles Griot Rotor Drive Shutters are compact and power-efficient through the use of bi-stable rotary solenoids.   The shutters have been proven in extremes of temperature and under severe shock and vibrations and operate reliably for several million cycles.  RDS shutters can be driven by the RSC450 controller.  The RDi shutters include on-board compact control circuitry that permits direct control by TTL level circuits. The LSC shutter controls low and medium power laser beams up to 6mm in diameter,

Picture for category Flag Shutters

Flag shutters are comapct, economical shutters that are relaiable under extremes of temperature and shock.  Custom blade shapes  are easily provided.  Flag shutters can include an optional blade position sensor.  Blades surfaces exist for thermal imager calibration and to shutter optical and laser radiation.

Picture for category Paddle Shutters

Paddle shutters are comapct, economical shutters that are relaiable under extremes of temperature and shock.  Custom blade shapes  are easily provided.  Paddle shutters can include an optional blade position sensor.  Blades surfaces exist for thermal imager calibration and to shutter optical and laser radiation.

Picture for category RDS Shutters

RDS shutters are designed for highest reliability under extremes of temperature, shock and vibration.  The shutters are designed as a single-blade 15mm aperture or multiple blade 18, 28, 35, 45 and 58 mm apertures.  Configurations exist with blade sensors and/or temperature sensors.  Blade surfaces can be used to calibrate thermal sensor or to shutter optical or laser radiation.

Picture for category Laser Shutters

Laser shutters have blades resistant to medium power lasers.  Gold blades control power beams at wavelengths above 650 nm.  Aluminum blades are used for wavelengths below 650 nm.  Safe-Close shutters automatically close the blade on power loss.  The RDi shutters are bistable and include a controller and blade position sensor.  Other shutters, including UTS solenoid-spring shutters, can be provided with gold blades.

Picture for category Shutters with Integrated Controller

These shutters offer the same capabilities and performance characteristics as our regular Rotor Drive shutters, with an integrated controller.  The controller is operated by a single TTL line that opens the shutter when high and closes the shutter when low.  A second TTL line provides a signal from on-board sensors for blade state.  The built-in controller enables rapid integration into your application with minimal investment.
