Flat-Top Beams and Plateau Uniformity Calculations
Beam Profiling Concepts |February 26, 2016
A flat-top beam (otherwise known as a top-hat) is used in various applications where a controlled profile is desired (i.e. a uniform density across the irradiated surface). Passing a Gaussian beam through special optics will create the flat-top beam and is the most common way of generating a flat-top beam. Uniform excimer beams are used in many material processing applications (e.g. creating integrated circuits). Industries such as welding, drilling, and medicine also make extensive use of flat-top beams.

Events |February 12, 2016
DataRay will be attending both SPIE BiOS 2016 (booth 8842) and SPIE Photonics West 2016 (booth 2239) in San Francisco.
Image Degradation Diagnosis and Filter/Sensor Cleaning
Application Notes |January 21, 2016
Although DataRay does not recommend cleaning beam profiling camera sensors due to the delicacy of the parts, cleaning may become necessary if dirt is interfering with the quality of laser beam profiling measurements. If the user decides to clean the sensor, we recommend extreme caution as user-damaged sensors are not covered by the camera’s three-year warranty.
Tutorial: WinCamD and BeamMap2 Interface to Labview
Interfacing |January 6, 2016
We are pleased to announce a new LabVIEW interface tutorial for both our WinCamD image profilers and BeamMap2 scanning slit profilers. The interface tutorial includes new LabVIEW interface examples which can easily be modified to suit a great variety of applications.
Beam Profiling for Small Beam Widths or Spot Size
Beam Profiling Concepts |September 14, 2015
Beam width or spot size is an important parameter to identify in selecting the optimal beam profiler. Scanning slit beam profilers are ideal for measuring small Gaussian beams.
