RGB detection

Other Parts Discussed in Thread: OPT3001, OPT101

Dear Sir,

Can I use OPT3001 to detect RGB color ? Thanks

  • ,

    Presently the OPT3001 detects light as the human eye sees it - I imagine that with some color-filters, you could probably isolate R, G, and B light and measure those wavelength passbands accordingly.  You would have to scale up the R and B to match the intensity of the G since the G has the highest response.  I also would imagine you would need to do some testing and calibration, possibly with a monochrometer, to make sure you're scaling the output accordingly.

    You would also need 3 OPT3001 devices to do this, or one with automated, adjustable filters.

    Might I ask the application and desired specs?

  • Just a heads up, the OPT101 data sheet has a color detection example now in the applications section.
