I updated some of the forum settings; please try again uploading the files it should work now

a view from the top of the spectrometer is also useful for debugging

Hi LaurenM, I don't see the attached file. Could you upload it again? One possibility (to be checked) which happens often is that you might be looking at the 2nd order of the grating which doubles the dispersion of the grating (the spectrum therefore spans on twice the range). You can already check ...

Yes, resin prints tend to be very brittle. For the cuvette, I recommend SLS technology. Resin is essentially useful when you want very small details like in the laser holder.

Hi,

That's normal -- you cannot connect twice to the camera

It's a common problem people meet but there is nothing to do, it's just that the camera is not made to support multiple connections.

Can you open spinview and take a screenshot of the camera list ? without doing anything else

Hi,

Can you double check the followings ?

• is the spinview software closed when you try to connect to the camera using SpectrumAnalyzer?
• is the ip address of the camera in the valid range ?

If it keeps blocking we can organize a TeamViewer session.

Not on my side; I'm currently working with Xometry even though I also worked for years with different companies in China and Singapore at my former employer. $109 isn't a lot -- I think Xometry would charge twice that. Don't waste your time with imalize (France) by the way, while they do have good q...

3.45 µm pixels, monochrome, very low absolute sensitivity threshold and at least 2048 px horizontally if you're using a 50 mm lens. The FLIR camera I'm using has a IMX265 sensor so you can look at substitutes that relies on the same sensor (in monochrome). Apart from the FLIR and Daheng cameras alre...

Sorry, my bad -- for some reason when I googled for the GC1380H it proposed a datasheet for another model and I didn't pay attention to the model number :shock: Here is the correct one : https://www.alliedvision.com/en/camera-selector/detail/prosilica-gc/1380h/ The absolute sensitivity threshold is ...

I looked up on Internet to gather some data on this camera model and I found this page : https://vitalvisiontechnology.com/allied-vision-manta-g-145b-poe/ It's an old CCD sensor (ICX285) with a not-so-good light sensitivity. The website mentions an absolute detectivity threshold of 11 e- with a quan...
