Problem with my new spectrometer from Aliexpress « on: March 04, 2026, 11:21:22 AM » Author: dor123
I bought this spectrometer from Aliexpress. However it have problems as you can see from the attachment, where it can't capture the correct spectra of lightsource like my Osram HCI-TS 70W/830. Also: I don't know how to import spectra to my computer with it. Why this is happening?

Maybe you need to calibrate it? Use a light source with known wavelength (either lasers or gas discharge lamps) to calibrate the spectrometer. Keep in mind don't point lasers at the spectrometer directly, point it towards paper.
