Abstract:
1. A method of adjusting the intensity of a beam of electromagnetic radiation comprising the steps of: a) providing: a beam of electromagnetic radiation which has been collimated; and a combination of: b) causing said beam to reflect from said reflecting means and monitoring the resulting effect on intensity while applying a means for sequentially placing different regions of said attenuation system in the path of said beam of electromagnetic radiation to position a desired region thereof in the path of said beam, said beam being directed to enter a detector after passing through said means for sequentially placing different regions of an attenuation system in the path of said beam of electromagnetic radiation; said method further comprising at least one selection from the group consisting of: storing at least some data provided by said detector in machine readable media; analyzing at least some of the data provided by said detector and storing at least some of the results of said analysis in machine readable media; displaying at least some data provided by said detector by electronic and/or non-electronic means; analyzing at least some of the data provided by said detector and displaying at least some of the results of said analysis by electronic and/or non-electronic means; causing at least some data provided by said detector to produce a signal which is applied to provide a concrete and tangible result; analyzing at least some of the data provided by said detector and causing at least some thereof to produce a signal which is applied to provide a concrete and tangible result.
