Experimenting With POF (plastic optical fiber) Part III

A project log for 3D Printable Raman Probe

This time I am using my 6500K CFL (compact fluorescent lamp) at two different exposure settings: 1) F-stop @ 5.6 and F-stop @ 10.

As you can tell though, the plastic fiber is really noisy no matter how I try and clean up the signal, either in the Nikon capture software or in Spectragryph processing software, still it is an interesting experiment because this is the same type of optical fiber that is used in the automotive manufacturing industry today because it is inexpensive, reliable and easy to work with.

My original project I had in mind for it was a fiber optic telecommunication's device using a photo transistor as the light transfer medium, who knows I still may strike that project back up :)
