Beam profiler
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 beam profiler is used to measure the beam characteristics.

Beam profiler of Kokyo / Customer’s Reviews
- Camera is inexpensive, so don’t worry about breaking it.
- Camera can be used as disposable.
- Easy to prepare.
- The software is intuitive and easy to use.
- Inexpensive.
- M2 beam quality measurement is included as a standard feature, which is very nice.
- The evaluation results showed that the software works as expected, so we have just ordered the software. (used the evaluation version before purchasing)
- Kokyo’s beam profiler has been installed into our device and we find it very useful.
- Just Irradiating large diameter laser light makes easy measurement.
- This is only product/device to be able to evaluate laser from LiDAR and we find it vey helpful
