For over 28 years, Spiricon has been the leader in laser beam profiling. Spiricon systems provide all you need to profile both pulsed and CW lasers from W to Watts. Some 15 models of silicon cameras, along with our exclusive Pyrocam pyroelectric camera and various accessories allow measurements: From the deep UV to the far infrared From micrometer sized focal spots to large beams From very low powers up to kilowatts. Spiricon CCD beam profilers include hardware and software features designed to handle every measurement need. Conformance to ISO 11146 requirements is virtually assured > Ֆ...

With LBA-FW, connecting multiple FireWire cameras is a snap. LBA-FW facilitates synchronizing the cameras in order to capture single events simultaneously from several locations. Allow the event to trigger the cameras, or setup a corresponding external trigger. Ultracal sets the baseline precisely. Beam width calculations become the most accurate.With the baseline set too low, laser wings are clipped off in the A/D converter. Calculated beam widths are now too small. With the baseline set too high, the algorithm interprets the baseline as wings in the laser beam. Calculated beam widths are...

User-selectable Z-axis scaling > When the signal is too weak to adequately display on the screen, Z-axis scaling recovers the detail that cant be readily seen. In addition, Z-axis scaling allows you to examine energy in the wings of a beam even if the peak signal was large enough for normal display. Since beam data is stored in raw form, Z-scaling can be applied whether recording the beam live or analyzing data by post-processing days later. Viewed at 1x, the Z-axis provides little detail (left). At 8x the weak signal can now be examined easily (right). Without Ultracal, the DC baseline...

Peak location scatter plot with histogram color-coding. A pointing stability strip chart presents data over time for the Centroid X and Y, Peak X and Y and centroid radius from an origin or from the mean centroid.The radius is referenced from either an Origin established in LBA or from the continuously calculated Average Centroid position. A centroid location scatter plot with histogram color-codingAny notations entered here will be printed with the charts. Notes remain from one reset to the next and from one application startup to the next.Set a sample limit, and specify the results items...
