Order code

Insert optical filters into a fiber optic pathway

  • In-line filter for SMA terminated fibers
  • Collimators for UV/VIS/NIR
  • Filter diameter 8–25.4 mm
  • Filter thickness 2–10 mm
  • Allows the insertion of optical filters within a fiber optic pathway


  • No stray light
  • Solid design


  • Stray light filtering
  • Removal of excitation light in fluorescence detection

This In-Line Fiber Optic Filter Holder allows the insertion of optical filters within a fiber optic pathway. The connectors of the filter holder assembly are com­pat­i­ble with WPI’s range of fiber optic jumper cables and can be coupled using SMA connectors. 

Filters with outer diameters from 8 to 25.4 mm and thick­ness­es from 2 to 10 mm can be accomodated. The design lim­its lateral and axial movement of the filter when secured in the holder.
Two fiber optic collimators are internally mounted in the holder to pass collimated light through the filter and then refocus the filtered light into the aperture of the out­put fiber. Spectral range will be largely limited by the bandpass of the optical fibers (from UV to near IR using WPI UV-enhanced ca­bles).
