At Arcadia, they were using standard (non-cooled) FLIR camera. But I'm planning on testing TEC cooled sensors for astrophotography although this will require some drivers to be written.

About the laser, you can use more than 100 mW but beware of the downside (optics must be able to handle more ...

Hi,

You can upgrade to a cooled CMOS sensor and use a 100 mW or 200 mW green laser and keep the budget well below 10k.

Concerning the performance, Arcadia published a paper comparing the starter edition (4.5 mW laser w/ loose resolution) to professional spectrometers : https://arcadia-science ...

Is there a good way to contribute notes/potential updates to the OpenRAMAN website? Would love to help out if possible on updating the LD/TEC board BOM and incorporating useful info like how the saturation/positioning lines work in SpectrumAnalyzer. There are also great posts on calibration ...

Thanks for this awesome post!

I was really surprised to read the prices of JLC CNC and I'm really wondering how they can achieve that. They're one tenth of the price of XOMETRY and the complete baseplate is cheaper than a raw stock of T6061

I guess you are using the BFS and not the BFLY version of the camera ; the problem was already addressed here : viewtopic.php?t=15

there's a dll to download to fix the issue

Hi Luc,

I am from India and had been looking for a cheap reman spectrometer for graphene. Literally struggling to find one. Had been doing test with Renishaw with one university, but now they don't want to continue anymore. Basically, I found that we need to do area mapping raman for graphene ...

you need to use the exact version provided with the software or recompile for the new SDK version

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
