High Detector Resets & Poor Resolution on some JEOL Microscopes

Description: 

 

Some JEOL Microscope Stage LED's cause High Detector Resets & Poor Detector Resolution

 

Environment:

  • Noran System 6
  • Noran System 7
  • Pathfinder

Resolution:

  1. Contact JEOL to inquire about the possible need for the JEOL installation of the JEOL option "R-Products". This option is totally controlled, installed, and supported by the OEM, JEOL. This option/modification disables the JEOL Stage LED's when the stage is stationary.
     
  2. The LED's are active ONLY when the stage is moving. After a stage move, the LED's are disabled again until the next stage move request.
     
  3. LED illumination degrade the performance of Thermo's  Microanalysis X-Ray detectors causing high resets and poor resolution.
