This Halation Eliminated Filter is newly developed filter for UV light for fluorescent PT and MPT, that eliminates obstacle visible light (404nm-424nm and 680nm-780nm).


  • Flaw indication contrasts finely with the background surface of the workpiece since fluorescence emission is not affected by visible light
  • Better observing condition for eyes of inspector
