Congratulations for your work

May I ask what is the purpose of the shutter ? Can't you shine the laser non-stop ?

I would try scrapping it off; mine didn't come with that green goo :/

Yes using a neon lamp it's possible - it's the way I calibrate all the spectrometer that I sell

making a cli program for linux has been on my todo list for a while now; feel free to start one because I don't think I will have time soon to work on it :/

The fishing wire + 2216 is just the state of the art; you can change gluing method if you can't access the one prescribed.

For the epoxy glue, just mix thoroughly the two components and apply a few dots only on the surface. When you place the grating, gently press it with a shearing movement to ...

Hi,

That looks like a standard laboratory LD driver with TEC - it should work like a charm!

Hi Young,

All the files (STEP, bill of material) of the starter edition can be downloaded here : https://www.open-raman.org/build/starter-edition/download/ and here for the performance edition : https://www.open-raman.org/build/performance-edition/

There are also upgrades to go from the Starter Ed ...

The morovian are actually relatively cheap cameras ; but they are not "true" cooled cameras as they are not made to work for extended period of time (they aren't fully sealed).

My plan was to TEC cool a regular camera just above dew point. But I have been quite busy this year and it's unlikely that ...

I would not necessarily recommend this sensor for two main reason:

the pixel size which is incompatible with the current spectrometer; this would require changing the imaging lens and hence a complete re-study of the pupil effects
single line sensors are a pain to align. I did it in the past and ...

You can definitely used the fiber-coupled add-on then :)

About the CCD/CMOS, that used to be true ~20 years ago but today CMOS have outperformed CCD even in long integration time. It is very difficult to have number for thermal constants which makes datasheet comparison difficult, but we can have a ...
