Perex
These shutters are based on translating mirrors that direct the laser beam to a beam dump, preventing it from propagating and protecting down-beam components and personnel. A pneumatic actuator moves the mirror into or out of the beam. By storing energy as compressed air, reliable, fast and fail-safe closing is guaranteed, even when mounted horizontally.

Features
- Pneumatically actuated
- In-air and UHV compatible options available
- Versions for large beam diameters ( >20cm ), high intensity (PW-class) and high average power (kW)
- Rapid closing times even for large mirror masses
- Constructed mainly from off-the-shelf industrial, high-reliability components
- Lifetime tested to > 10000 cycles
- Numerous models developed for different applications
- High reliability closing even in a horizontal orientation
Benefits
- Simple, high-reliability control with compressed air
- Adaptable design for demanding physics applications
- Suitable for integration into large laser systems
