Re: [DIYbio] Re: Does Anyone Know Of A Submersible Arduino/RaspberryPI Compatible Spectrometer?

Thorlabs has fiber bundles that are easy to couple (https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=5609). Probably just need appropriate size and some kind of mount with a linear stage (TL also has all of these) if you want to be really fancy but I would say that these are pretty easy just to fix manually to the entrance of spectrometer. Spectrometers have entrance slits of about 1mm (depends on resolution you need) so choose bundle with that kind of diameter (inner).

That's one hell of a shipping charge on a $35 item, thanks though, it's worth looking at how those are made to see if it's going to be cheaper than trying to convince Thor Labs to build me the fiber components or getting a fusion splicer myself.
