15 Mar 2007 The USBeamPro 10-bit CMOS camera with USB 2.0 computer interface is a small and easy-to-use beam profiler. USBeamPro software provides accurate measurements of ISO Standard beam profile parameters. USBeamPro calibration is NIST traceable. The USBeamPro is a camera-based beam profiling system with USB 2.0 connectivity, operating under Photon's renowned BeamProfiler Software in Microsoft Windows. 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 1280×1024 array with 6.7µm square pixels; for a total beam imaging area of 8.6mm×6.9mm. The camera's small form factor of 54×54×33mm allows ease of placement into typical optical paths. The nominal dynamic range of this array is 30dB (10-bit digitization). Profiles with greater than 48dB (>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.
