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.

or

# via conda
conda install -c conda-forge seabreeze

Usage

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()
array([  1.58187931e+01,   2.66704852e+04,   6.80208103e+02, ...,
         6.53090172e+02,   6.35011552e+02,   6.71168793e+02])

To use the pyseabreeze backend (requires pyusb) simply run this before importing seabreeze.spectrometers.

>>> import seabreeze
>>> seabreeze.use('pyseabreeze')
>>> import seabreeze.spectrometers as sb
