I'm surprised about the low resolution of the paracetamol peaks despite you're using the higher quality laser.

If you take a spectrum of isopropanol do you get a sharp peak? If not it could mean that the laser is not operating at its best operating point (temperature and current)

Hello Jerry,

It's common during the first alignment. Laser steering is usually the problem so check with the frosted disks that you get proper centering on each aperture.

Hi Jerry,

You may want to have a look at the articles I wrote on the topic:

I did not know about the link you gave. There are other online spectral database but they aren't free; reason for which I tend to stick to SDBS. About the powder, I recommend you press it but not necessarily with an hydraulic press. I just use the back of a drill bit to get something flat. It's not ...

Getting the signal can be difficult the first time. Can you try repeating the alignment process using the two frosted disks w/ pinholes?

The calibration looks fishy :-/ I'd say the spectrum needs to be moved to the right.

Just to check, What camera and imaging lens are you using?

This is unusual. Can you start the evemon.exe program first then the spectrum analyzer one? It will capture a trace of any error thrown in the debug process

I think you can even do it without having to do any programming by writing on the user set as explained in flir's post... worth to be tried!

My apologies, I though you wanted to trigger acquisition via hardware. I now understand that you want to enable an output during the acquisition process which is much simpler to implement. Generally speaking, all cameras features can be accessed via a "Property" object in the code which ca...
