This software is not associated with Ocean Optics. Use it at your own risk.

DISCONTINUED

I do not work on this module anymore. Please switch to its successor python-seabreeze.

INFO

The complete python-oceanoptics PyUSB interface is now merged into the pyseabreeze backend from python-seabreeze. As soon as all spectrometers are tested with python-seabreeze, the python-oceanoptics module will be obsolete. So if you own any of the untested spectrometers, please test it with python-seabreeze and let me know if it works. Thanks.

Ocean Optics python module

This python module provides access to some basic functionality of some Ocean Optics spectrometers. The lack of availability of a python interface for their spectrometers lead to the development of this module. The specifications of the USB communication layer used in their spectrometers are freely available in the OEM manuals on their website.

This software is a community effort to get platform independent python support for these spectrometers. If you are not 100% sure what you are doing, stick with the - also platform independent - SpectraSuite and OceanView software.

Currently working with:

• USB2000+
• USB4000
• QE65000
• STS (Note: The rewritten class supports protocol version 0x1100)
• USB2000
• USB650

Might work, untested:

• HR4000
• QE65pro
• HR2000+
• HR2000
• apex
• maya
• maya2000pro
• Torus

Not yet supported:

• Jaz
• NIR
• NIRQUEST

Contributions are welcome.

Installing

Requirements

I'm using python 2.7.x, so this is not tested on Python 3.x.

The core libraries require:

• pyusb-1.0.0b1 (this is available on pypi. Newer versions break parts of the API...)
• numpy

For the example you'll need:

• gtk3 python bindings
• matplotlib

Linux

To install the python module download this repository and run:

python setup.py install

You should also install the udev rules:

sudo cp misc/10-oceanoptics.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules

make sure that your user is in the plugdev group.

Windows and OSX

If anyone wants to volunteer to write instructions how to use this library on Windows and Mac, feel free to contact me.

Quickstart

After installing test if it's working by:

import oceanoptics
spec = oceanoptics.get_a_random_spectrometer()
print spec.spectrum()

or run the example program liveview.py
