Ocean optics SR4 spectrometer (USB 4000)

Hardware Issues
1

Hello sweepme team

Ocean optics SR4 spectormeter is a same model as usb4000, but it’s a new version.
So I connected ocean optics SR4 spectrometer.
But I couldn’t connect the spectrometer to sweepme.
How can I address this problem?

Hi Jeonghwan,

maybe you have the same problem as discussed in this issue:

It could be that you need to install the OceanView software first that also installs the hardware driver for the spectrometer. Afterwards, you should find the Ocean optics spectrometer in the Windows device manager.

If this is already the case, it might be that the library python-seabreeze that we use to interface with Ocean Optics spectrometer does not support your newer spectrometer yet which would mean that we need to adapt our SweepMe! driver.

First, let’s make sure that your spectrometer is properly installed and shown in the Windows device manager. Can you run it with Ocean View software?

Best, Axel

On the webpage of the python-seabreeze library I found some code to test which models are supported yet:

import seabreeze.cseabreeze as csb
api = csb.SeaBreezeAPI()
print(api.supported_models())

If run this code in the Python Script Tool of SweepMe! (via menu “Tools” → “Python Script”, I get the following result:

[‘Apex’, ‘FlameNIR’, ‘FlameX’, ‘HR2000’, ‘HR2000Plus’, ‘HR4000’, ‘Jaz’, ‘Maya2000’, ‘Maya2000Pro’, ‘MayaLSL’, ‘NIRQuest256’, ‘NIRQuest512’, ‘QE-PRO’, ‘QE65000’, ‘STS’, ‘Spark’, ‘Torus’, ‘USB2000’, ‘USB2000Plus’, ‘USB4000’, ‘Ventana’]

It looks like that your model is not yet supported by python-seabreeze and our SweepMe! driver.

There is the possibility to add further models to python-seabreeze and thus to our SweepMe! driver.

If your problem is not solved by installing the hardware driver, we can offer to support you with adding this functionality. In this case, please write us to contact@sweep-me.net

Thanks and best,
Axel

A list of supported spectrometers can be found here as well:

The SweepMe! driver uses the cseabreeze backend so it looks like that the SR4 is not yet supported.

After some further research, it came out that newer Ocean Optics spectrometer such as the model SR4 are not compatible with our existing USB4000 instrument driver.

There is a new software development kit (SDK) provided by Ocean Optics called OceanDirect:

Anybody who is interested in using newer Ocean Optics spectrometers with SweepMe! please write to support@sweep-me.net and we can offer to support you with creating a SweepMe! driver.

I have good news for everbody with a new Ocean Optics spectrometer:

In one of our latest projects we created a SweepMe! driver for the Ocean Direct SDK that is used to interface the newer models of Ocean Optics spectrometers:

The driver is now publicly available and can be used by everyone.

Any further user feedback is welcome.
