Ocean Optics USB4000 Spectrometer

Shib,

You'd better start a thread next time you have a question. This one is out dated.

Labview (and other programming languages) drivers for Ocean Optics spectrometers USB2000 and USB4000 can be purchased at Ocean Optics website. They're not good quality though and may not work with Labview 6.1.

Thnx...:)

Hi,

I read your post that you worked on ocean optic's USB4000 VI.  I am a chemical engineer and want to automate my analysis which involves USB4000. It is kinda hard for me to get the generic VI work for USB4000.  It would be a great help from your side if you could send me the VI's of USB4000.  My thesis work is struck at obtaining obtaining data from the spectrometer.

Hi Shib,

I have the generic driver and the programming manual with me. If you need then let me know. I can email them to you.

Hello all,

When making a call to the Ocean optics OmniDriver.dll with long integration times and or averaging, it seems Labview cannot do anything else until the OmniDriver "Wrapper" returns.  I would like to include some type of feedback to the user such as a progress indicator and or a blinking control.  Is there a way to do this?

regards,

Karl

Hey Karl,

Can you be more specific? I experienced some timeout issues with Omnidriver.dll too. Sometimes the OO spectrometer stays frozen for no reason at initialization.

I noticed that to get a corrected signal the spectrometer has to 'run several integration times'. I mean that there is a signal offset that is corrected run after run. I figured out that a bit less than 20 runs are necessary to to get a corrected signal.

I developed a progress indicator with LV whose total time is 20 runs * integration time. It doesn't communicate with the dll it just assess the necessary time to get accurate measurements.

Hi,

coming back to the original question posted by MAH: In our Lab, we had a similar problem with the OmniDriver-Package from Ocean Optics. See this thread: http://forums.ni.com/ni/board/message?board.id=170&thread.id=275400&view=by_date_ascending&page=2

We finally solved it, but with a trial-and-error-game 🙂

Hope this helps,

Christian

Can you please send me those VIs for Ocean Optics USB4000?

Thank you

MAH2681, I am also using the USB 4000 spectrometer and trying to integrate it into LabView 8.6 and having the same problem.  Would it be possible to get a copy of your VI you are using?
