Problem with set_integration_time, the spectrometer doesn't wait for spectrum acquisition. about python-seabreeze HOT 3 CLOSED

Hi @josue300earth

By default the spectrometer is constantly acquiring spectra. When you switch to a long integration time, the last spectrum taken at the short default integration time is still in the buffer.

If you run the following, you'll see that it'll take a 10 second spectrum:

from seabreeze.spectrometers import Spectrometer, list_devices
import matplotlib.pyplot as plt

devices = list_devices()
spec = Spectrometer(devices[0])

# set integration time
spec.integration_time_micros(10000000) # 10 seconds
_ = spec.spectrum()  # throw away last spectrum...
wavelengths, intensities = spec.spectrum()
plt.plot(wavelengths[10:],intensities[10:])

Let me know if that fixes your issue.

Hi Andreas, thank you for python code ad your quick answer. Well, here is my story; I did prove the code that you sent me, and it didn't work, so I talked with other lab partners, and they lent me another spectrometer; it turns out that the spectrometer that I work has some damage because the new spectrometer works perfectly with previous code. I repeat, thank you.

That's great! Happy to hear you found the cause.
I will close this issue now. Feel free to open another one in case there's anything else.
