In, and each between have connectedness, just can guarantee that detector detects fluorescence signal.But also bring along simultaneously mutual
Interference, so that testing result is inaccurate.The interference of fluorescence is excited to reduce other light to oil, so from optical filter to light
Filtered, but due to the current conventional minimum 10nm of optical filter bandwidth, OD values are 6, but in the very low feelings of oil content
Under condition, fluorescence excitation efficiency is less than 10-6, and the OD values of a tablet filter are up to 6.Exciting light in fluorescence is not had very
Good filter action, so that exciting light produces larger interference to fluoroscopic examination, simultaneously because the fluorescent belt received is wider than width,
