Laser shutters are safety and control devices used to block or transmit the laser beam on demand. They are typically installed near the source and serve as the first line of control in a laser system, either as part of an interlock circuit or for process timing.

In a beam delivery system, shutters are often mounted directly after the collimator or beam expander, allowing the beam path to be physically interrupted during startup, fault conditions, or when the system is idle. Some shutters are also used for beam modulation in low-duty-cycle applications.

Haas offers both manual and electrically actuated shutters, including models compatible with fiber and CO₂ systems. All are designed for high reliability, repeatable blocking, and seamless integration with safety and control systems.

Select the series that matches your beam delivery system:

• 19 mm, 25 mm, or 38 mm

The aperture should be at least 2× the beam diameter to avoid clipping.

• SSDP Models
  For low to moderate power levels. Passively cooled and compact.
  Example: SSDP-25 for up to ~500 W fiber or CO₂ lasers

• SSHP Models
  For high-power applications. Integrated water cooling supports continuous operation at multi-kW power levels.
  Example: SSHP-38 for up to 5 kW

Some shutters are available with an integrated diode pickoff. This allows a small portion of the beam to be monitored for power or alignment without affecting the main beam path.

Choose this option if:

• • You want continuous power monitoring during operation
  • You plan to align the system using a detector or camera

• Use the standard base plate or mounting collar to secure the shutter inline with the beam path
• Ensure the orientation allows the blade to open and close cleanly without obstruction

• Connect the shutter to your safety system or motion controller
• Use the provided 24 V signal input to open/close the blade
• Confirm interlock logic matches your laser controller (fail-safe configuration recommended)

• Connect inlet and outlet lines to your cooling loop
• Check for proper flow and temperature regulation before enabling the laser

• Use the shutter to block the beam during warm-up or alignment
• Confirm blade fully closes with no light leakage when powered off
• In applications with multiple beam paths, use shutters to enable or disable specific legs of the system

• Always install shutters as close to the laser source as possible
  This keeps the upstream beam path safe during startup and emergencies
• Test your shutter function regularly
  Simulate a fault condition to verify the blade closes fully and quickly
• Use the diode pickoff for passive beam monitoring
  This is useful during production or when using power feedback loops
• Plan for maintenance clearance
  Shutters can collect debris over time — leave room for inspection and cleaning
• Tie shutter state to your machine interlock
  Don’t rely on software alone to disable the beam — use physical blocking wherever possible
• Use water-cooled versions for continuous high-power operation
  Passive shutters may overheat under sustained multi-kW use
