The USBeamPro is a camera-based beam profiling system with USB 2.0 connectivity, operating under Photon's renowned BeamProfiler Software in Windows™, which includes Vista. It provides highly accurate measurements of ISO Standard beam profile parameters, including beam diameter, centroid, and power/energy. The USB 2.0 interface offers enhanced ease of use and portability.

The USBeamPro features a 2/3" format CMOS 1280x1024 array with 6.7µm square pixels; for a total beam imaging area of 8.6mmx6.9mm. The camera's small form factor of 54x54x33mm allows ease of placement into typical optical paths.

The nominal dynamic range of this array is 30dBpower (10-bit digitization). Profiles with greater than 48dBpower (>16-bit effective digitization) can be acquired with Extended Range Imaging. High dynamic range is important in many applications, especially lens characterization, where lens aberrations are apparent from faint features around a strong central peak in the beam profile.

This instrument provides a high level of portability for beam profiling, since a peripheral frame grabber card is not required for this system. Thus, this equipment can be easily transferred to different laptop or desktop computers without the additional step of installing a frame grabber card and the required software drivers into the computer.

USBeamPro Acquisition and Analysis Software
The USBeamPro Software is written specifically for MS Windows XP Pro, Windows 2000 Pro, and Vista, and takes full advantage of the menu driven, multi-windowing environment. The software performs rigorous data analysis in accordance with the ISO standards, providing quantitative measurement of numerous beam spatial characteristics. Pass/Fail limit analysis for each of these parameters can be also applied.

For data display and visualization, the user can arrange and size multiple windows as required. These may contain, for example, live video, calculated beam parameters and summary statistics in the form of graphs, tables, 3D views and strip chart time displays. These user instrument views can be saved as files for future use.

Data can be exported to spreadsheets, math and statistical analysis programs and process/instrumentation control programs by logging to files or COM ports, or by sharing using ActiveX Automation.
