• Open air laser marking machine

Open Air Laser Marking Machine  

The Open Air is an inline laser marker designed to provide direct part marking within your robot-assisted manufacturing process without using any costly part fixtures.

Parts are brought in front of the laser aperture by a robot, where a high-power fiber laser delivers repeatable and high-contrast markings. Part detection sensors dynamically validate part positioning to ensure the identifier's quality compliance and laser safety. Once marking is completed, the robots moves the part to the next operation of the production cycle. 

Benefits of the Open Air Machine 

Open air machine retrofitted in production cell

Leverage Existing  
Production Capabilities 

The Open Air machine can easily be retrofitted in existing production cells. By leveraging your robot’s precision and idle time, it minimizes the cost and complexity of adding part traceability to your process. 

manage multiple parts

Manage Multiple Parts and Cavities Without Fixtures

Avoid buying costly fixtures and use the robot’s gripper to hold the parts instead. Since the parts are not dropped onto fixtures, the marking process is simpler and can be adapted for various marking needs, including multi-part and multi-cavity production contexts. 

Robot's part position open air machime

Precise Adjustments to
the Robot’s Part Positioning 

In order to provide high code quality and reliability, the open air machine can be equipped with a Z-autofocus system and an X-Y vision system to guide the robot so that it presents the part to the laser marker with unmatched precision.  

flexible and compact footprint

Flexible and Compact Footprint

With its compact design and its adjustable orientation and height, the Open Air machine can be integrated into any production cell. In addition, its electrical cabinet and control panel can be remotely located to minimize the footprint as well as facilitate operations and maintenance. 

Integrated Dust and Heat Management 

To minimize maintenance and ensure long term performance, this laser machine is equipped with active dust and heat management. 

Instant Barcode Validation 

Achieve instant quality control for your markings. Our standard barcode validation peripheral identifies any uncompliant marking just after the marking operation, including data matrix codes, QR codes, serial numbers and so on. 

Class-1 Laser Safety Rating 

Safety is never an option. As a turnkey solution, this automated machine complies with international laser safety standards. It helps you create a 100% safe work environment without requiring personal protective equipment.

Laser Machine Options 

Laser Power 

The Open Air machine can be equipped with fiber lasers that range from 20W to 500W to meet all types of marking speed requirements.   

X-Y Vision System 

The vision system helps the robot position parts in front of the laser marker, reducing or eliminating X and Y positioning errors. You need it if part positioning variations are too high for the marking process. 

HMI Control Panel 

The standard HMI control panel provides direct access to laser marking parameters near the machine. You can: 

  • Manually adjust the laser marking zone, scale the identifiers, edit them and more 
  • Enter the manual operation mode to run tests or calibrate the laser 
  • Display information such as the system status, the operation mode and the alarm history 

If you want to add custom features in the HMI, contact us

Barcode Validation

Marking quality can be verified directly in the machine with our standard barcode validation system and precalibrated Cognex camera. 


To comply with the latest industrial traceability standards, Cognex’s VisionView can be integrated directly in our standard HMI to help you visualize reading results as well as perform maintenance and diagnostics on the barcode reader. You gain access to their standard views and database analysis tools, which can be used for production lot tracking, marking quality statistics and much more.
