DAMPER FOR SPECTROPHOTOMETER FOR ADJUSTING INTENSITY OF LIGHT AT REAL TIME WHILE MEASURING LIGHT BY EMBEDDING DAMPER INSIDE SHIELDING CABLE OF SPECTROPHOTOMETER

摘要

PURPOSE: A damper is provided to adjust the intensity of received light at real time selectively and gradually. CONSTITUTION: A filter(250) has a disk shape having the same diameter as the bore of a shielding cable. The filter is embedded between one end of an optical fiber and a second end of the shielding cable to be rotatable for selectively reducing the intensity of light. A handle(255) is arranged in the outer surface of the shielding cable. The handle rotates the filter by connecting with the filter. Thereby, the intensity of light is adjusted at real time during a measurement.
