Real Time Absorbance for Ocean Optics spectrometer with OmniDriver

[turtles]

Hi, I am new here.

I am developing a LabVIEW code to measure real time absorbance for Ocean Optics spectrometers with OmniDriver.

I used "SetAcquisitionParameters_NET" file provided by OmniDriver sample pack for multi-spectrometers.

It is working well for normal scope mode intensity measurement with integration time, average to scan, and boxcar width. But, I do not know how to collect real time absorbance data with reference and noise data like SpectraSuite software does.

Could anyone tell me how to program this?

Good Afternoon,

I am not sure what your exact spectrometer is, however, there are many drivers for Ocean Optics products at ni.com/idnet.  If there is a LabVIEW driver for you spectrometer here, then you can use the API within that driver to acquire the desired data.  Hope this helps!

Cody C,

Good Morning. I am using S2000 and HR2000 now. I will try what you suggest. Thank you.

Hello,

   As long as your S2000 has an USB ADD, you will be able to use it with OmniDriver-SPAM.  The HR2000 will work fine.

  Here are two good videotutorials that will show you how to use OmniDriver-SPAM with its LabView dll to acquire spectra:

  Hope this helps,

Forgot to add that for the Absorabnce, you need to use or have SPAM (Spectral processing and manipulation - OmniDRiver component). http://www.oceanoptics.com/Products/omnidriver.asp 

In SPAM you need to use the class: CoreAbsorbance

And the method is: processSpectrum()

Cheers,

Hello there, can u be more specific how to use the class with SPAM in labview especially to measure absorbance.

Hi,

  Please see attached example VI.   In Labview 8.6, 32 bits.

Thank you,

Hi sir,,

I have tried to run this program using LabVIEW 2014  64 bits.. but it has got problem with the NetCoreAbsorbance. Should I use LabVIEW 8.6 32 bits for running this program?

Really need this info.

Thank you

Hi R,

Thanks for your example. I really appreciate it. Can you share another examples to calculate CCT,CRI, Purity,x,y,Ra-R14? Hope to hear from you soon.
