High Power - ModeCheck™ - A New Method to Assure the Performance of High Power CO2 Lasers

  • Beam Profiler for collimated 50W-5kW, 10.6um wavelength, beam width up to 30mm.
  • Quality Cutting, Marking, Drilling & Ablating Require More Than Consistent Laser Power
  • Instantaneously “see” and measure the beam - reduce set-up time between jobs
  • Real-time “mode burns” - eliminate hazardous acrylic vapors
  • Optimize laser efficiency - reduce cost per part
  • Predict laser preventative maintenance - increase manufacturing efficiency

Death Of The Mode Burn
Importance of CO2 Laser Measurements
Watch the ModeCheck video
ModeCheck is designed for the industrial parts manufacturer to reduce the time it takes to change over between different jobs. The user can quickly place the ModeCheck in front of the laser and see and measure, in real-time, the laser beam profile to confirm optimal laser performance. In addition, and when used periodically, the user can compare measurement changes from the same set-up and make necessary laser adjustments, keeping the laser output constant for the same job from day-to-day. Over time the user will be able to see and measure laser degradation to predict and advance schedule down-time needed for periodic maintenance.
ModeCheck eliminates operator exposure to acrylic mode burn hazards while improving product quality and manufacturing efficiency.
In addition to both 2D and 3D graphical image display and save, the following measurements are made from each image:
  • Beam Widths and Diameters
  • Beam Position Stability
  • Power Density Peak
  • Beam Centroid Location
  • Elliptical Analysis with Major Axis Orientation
It’s just this easy.
  1. Remove Focusing optic
  2. Locate the beam center with pointing beam or similar device
  3. Place ModeCheck in beam center
  4. Turn on Laser
  5. Instantly see, measure and electronically store the beam characteristics
Optional Accessories
One must manage the pass-through laser beam by collecting the beam using either a power meter or beam dump. We recommend using a power meter as the additional measurement information will assist in managing laser optimization. Note that any beam dump or power meter large enough to handle 5kW will require water cooling. There are holes on the bottom of ModeCheck for mounting the Power Meter Head or Beam Dump.

A PC is required to run the ModeCheck imaging software. The camera is powered over the USB cable that connects the computer to ModeCheck.

A ruggedized storage/carrying case is highly recommended for safe and efficient handling.
  ModeCheck makes instantaneous beam measurements along with graphically displaying both the 2D and 3D power density distribution
