Imaging With Magnification Test Procedure

Although modern cameras have advanced to the point where pixel size approaches 4 microns, we have yet to achieve the submicron size necessary to accurately resolve focused laser beams. Present methods such as pinhole scans and knife edge scans assume spatial wave forms to fit the transmission, and those assumptions may be erroneous. This technical note details a method of imaging with calibrated magnification and commercial laser beam profiling software to accurately measure beam sizes. Experimental layout is detailed, all reference material included, and the equations stated.
