Laser Beam Delivery Components

Shutter

Overview

External shutters are engineered for fast, reliable laser beam blocking and interlock integration in high-power beam delivery systems. Designed to interrupt the beam path with precision, these shutters offer a fail-safe mechanism that protects downstream optics and operators during maintenance, alignment, or in the event of system failure.

Each shutter is available with an alignment diode and in multiple aperture sizes to match your beam delivery setup. Whether you’re working with low, mid or high-power industrial lasers, Haas shutters are designed to handle the job with long-term durability and ease of integration.

Applications

Shutters are widely used in industrial, medical, and scientific applications to ensure controlled operation of high-power lasers. They offer a dependable solution for beam blocking when machine access, servicing, or idle states require the laser to be inactive.

Laser Cutting Systems
Used to block the laser beam during setup, tool changes, or interlock conditions. By stopping the beam at the source, the shutter helps prevent stray energy from reaching downstream optics or components.

Laser Welding Cells
Mounted directly to the laser output bezel, these shutters provide a reliable means of halting the beam when the system is idle, in fault state, or during service operations. This helps protect equipment and maintain controlled operating conditions in automated welding cells.

Laboratory and R&D Environments
Well-suited for research labs, test benches, and prototyping setups where beams need to be selectively opened or closed. Shutters allow researchers to block the beam path quickly without disconnecting optics, streamlining system reconfiguration and troubleshooting.

OEM Laser Systems
Compact size and straightforward mounting make these shutters a practical option for OEM integration. They can be incorporated directly into laser subsystems, providing an added layer of beam control without taking up excessive space.

Selecting a Part Number

To configure the correct external laser shutter for your system, choose from the options below based on your application’s laser wavelength, power, and integration needs:

Step 1: Select an Aperture Size
Available in 19 mm, 25 mm and 38 mm series.
Choose the aperture based on your beam diameter, with 1.5x margin recommended to avoid clipping.

Step 2: Select Blade Material
Choose the shutter blade material based on your laser wavelength and power. Different coatings are available to optimize reflectivity, thermal handling, and durability.

Step 3: Choose Power Management Options
Options range from air-cooled designs to higher-capacity water-cooled versions, depending on your power level and integration needs.

Step 4: Define Detection Requirements
Select the level of position monitoring or interlock feedback appropriate for your system. Options include simple open/closed sensing, redundant sensors for critical applications, or external control when system interlocks are managed elsewhere.

Step 5: Add Optional Features
Consider additional options such as thermal monitoring (RTD or thermal switch) for temperature feedback, or an alignment diode for low-power beam alignment. These features can enhance usability and system integration when required.
