      If the main switch can turn the system ON but the mercury burner won't light, there are several potential causes. First, ensure all connectors are firmly connected. Second, check that the mercury burner is properly attached. Third, verify that the safety device in the lamp housing is correctly set up. Finally, if auto ignition is malfunctioning, try setting the main switch of the power supply unit to “ ” (OFF) then “ I ” (ON) again. This OFF/ON sequence can be repeated.

Third, ensure the fluorescence mirror unit is correctly engaged in the light path. Fourth, fully enlarge the aperture iris diaphragm and enlarge the field iris diaphragm until it circumscribes the field of view. Finally, make sure the fluorescence mirror unit matches the specimen.

      Thomas BurnsAug 29, 2025
      If the mercury burner flickers or is dark on your Olympus Microscope, it could be due to several reasons. If it is soon after ignition, allow it to run for at least 10 minutes. If the hour counter indicates 300 hours (USH-103OL, HBO103W/2), replace the mercury burner. You may also need to center the mercury burner.
