Comparison between LaseView-LHB and conventional products
For high power

Right: Beam profiling with at one time with LaseView-LHB.

Conventional Beam profiling measurement with high power laser needed damping system because CCD camera may be easily destroyed.
LaseView-LHB can measure as much as maximum 100 W/cm2 laser beam without additional attenuation system by using a newly designed optical system.
It simplifies optical system and prevents introducing distortion on laser beam.

For large diameter

Until now, Beam profiling measurement with large diameter has required measuring by dividing it in several parts by making manual movement on the conventional profiler. It takes time and energy and also, divided measurement makes laser relative intensity unclear. LaseView-LHB solves such problems and it becomes possible to make large beam profiling at one time.
Scanning laser measurement
Laser analysis of LiDAR using multiple LHBs
Because the aperture is wide, laser scanning light can be measured with a laser scanning unit without moving the beam profiler. Not only the beam profile but also the position of the laser beam can be accurately identified, making it ideal for performance evaluation.
Main Analysis Functions
Ｍ2 beam quality Analysis function
It is an important parameter for focus or processing, it can be easily measured with standard methods. The procedure of the optical system setting is described below:
M2Fig: M2 measurement screen
- The laser beam shall be focalized through a lens with f-number (focal length/beam diameter)between ~50 to ~100.
- Install a ruler or an optical rail along the beam so that the CCD camera can slide in a range of ±50mm～±150mm around the beam waist.
- click on the “Collective analysis” of the “M2 beam quality” tab.
See the “About beam profiler” tab for more information.
Divergence angle Analysis function
Beam divergence angle is an important parameter for light propagation characteristics which can be easily measured with a standard method. Its measurement’s procedure is described below:
Fig: Beam divergence angle measurement screen
- Measurements taken at 2 or more positions shall be saved in the same folder.
- Click the “Divergence angle” button of “Collective analysis” tab.
In addition, as the measurements are made at different places, it is possible to evaluate the change in power and thus the propagation loss.
Beam pointing variation Analysis function
The Beam pointing stability varies with time and is an important parameter for Laser Beam stability which can be easily measured with a standard method. Beam pointing measurement procedure is described below.
Fig: Beam pointing stability screen
- Use the image logging function, and save images taken at an appropriate time interval.
- Click the “Pointing” button.
- Click the “Execute analysis”.
The changes over time of X and Y coordinates of the beam centroid will be displayed in a graph.
