Laser Beam Profiler

Laser Beam Profiler is an instrument that measures the beam diameter and spatial intensity distribution of a laser. The beam diameter and spatial intensity distribution are laser characteristics that describe how the beam will behave.

For example, even if a laser has the same intensity and beam diameter, if the spatial intensity distribution is different, the focusing characteristics will change, and the same behavior will not be obtained. In addition, even if the laser cavity is rigorously designed, it is affected by manufacturing errors in the optical elements and the surrounding environment such as temperature. Therefore, it is difficult to accurately predict the beam characteristics to be obtained.

For this reason, it is important to measure the actual beam characteristics in laser beam applications.
A Laser Beam Profiler is used to measure the beam characteristics.

Laser Beam Profiler / Type and Pros & Cons

Fixed Laser Beam Profiler system with CCD camera is adopted on Kokyo’s products.
Here are advantages and disadvantages between scanning Laser Beam Profiler system and fixed Laser Beam Profiler’s one.

Advantage Disadvantage
Fixed Laser Beam Profiler
・CCD camera type
  • Short measurement time
  • Pulse light measurable
  • Complicated beam pattern identifiable
    (flat-top or donut-shaped etc)
  • High-cost
  • Micro beam diameter measurement is difficult

※ Kokyo’s Laser Beam Profiler is low-cost and can measure large beam diameter

Scanning Laser Beam Profiler
・Pinhole type
・Slit type
・Knife Edge type
  • Easy measurement
    on Micro beam diameter
  • Short measurement time
  • Pulse light measurement is difficult
  • Complicated beam pattern measurement is difficult

Laser Beam Profiler of Kokyo / Merit & Advantage

Commercially sold CCD camera or CMOS camera is available on Kokyo’s Laser Beam Profiler and so,
low-cost and practical beam measuring system can be easily structured.

Also, due to low-cost cameras, beam monitoring system with multiple cameras can be structured with low-cost on Kokyo’s system.
