Python module for Ocean Optics spectrometers
Python-seabreeze is the easy way to access your Ocean Optics spectrometers from python. It wraps the SeaBreeze library provided by Ocean Optics to communicate with the spectrometer. It also provides a pyUSB based reimplementation of SeaBreeze for easy extension. This software is not associated with Ocean Optics. Use it at your own risk.
You'll find the documentation and more detailed information here https://python-seabreeze.readthedocs.io/en/latest/
The changelog can be found here CHANGELOG.md
# via pypi
pip install seabreeze
seabreeze_os_setupor
# via conda
conda install -c conda-forge seabreeze
seabreeze_os_setupThe backend pyseabreeze requires the libraries pyusb and libusb
# via pypi
pip install seabreeze[pyseabreeze] # this ensures installation of pyusbAdditionally, you might need to manually install libusb1. Go here https://libusb.info/, Downloads -> Latest Windows Binaries. In the zip file, enter either the folder MinGW64/dll or MinGW32/dll (depending on your OS). Copy the file libusb-1.0.dll into C:\Windows\System32.
The following example shows how simple it is to acquire a spectrum with python-seabreeze through the model independent Spectrometer class. For a more detailed description read the documentation:
>>> from seabreeze.spectrometers import Spectrometer
>>> spec = Spectrometer.from_first_available()
>>> spec.integration_time_micros(20000)
>>> spec.wavelengths()
array([ 340.32581 , 340.70321186, 341.08058305, ..., 1024.84940994,
1025.1300678 , 1025.4106617 ])
>>> spec.intensities()

>>> import seabreeze
>>> seabreeze.use('pyseabreeze')

This functionality is currently implemented for the HDX with the pyseabreeze backend. The following example shows how to read a spectrum via ethernet:
>>> import seabreeze
... from seabreeze.spectrometers import Spectrometer
...
... seabreeze.use("pyseabreeze", network_adapter="192.168.254.200")
>>>
>>> spec = Spectrometer.from_serial_number("HDX12345")
>>> spec.intensities()
