Spectroscope to bin near-UV LEDs from AliExpress

I bought a few 1,3 and 5 Watts 400-410nm LEDs from AliExpress shops and I wanted to confirm and/or select the correct 405nm wavelengths out of these for a 70-100 Watts panel.

For this purpose I designed a small FDM-printable spectroscope.
Details and models can be found here: https://www.thingiverse.com/thing:3351995

Maybe this is something of use for others here as well.

Cheers!

Neat! Did you make any modifications to the webcam for IR or UV performance?

I may have to play with this, as I have an Ocean Optics USB4000 that I can use to compare against.

Yes, I removed the IR filter glass from the objective but near-UV works without any modification as well.
