    hiii,

    i want the working of opt101 for fluorescence..
    can opt101 work for flourescence..

    if any1 knws plzz help me out.

    thank u

    What color does the fluorescence appear 2b?

    Is that a question?

    If you can see the fluorescence, so can the TI device.

    i knw tht opt101 can be used for absorbance
    bt i want 2 knw whether this will work for fluorescence..
    here im using uv led for fluorescence..
    n if it works than what is the working of opt101

    or which other ic can be used for both fluorescence and absorbance

    1) Maybe if you wrote with English spelling and not text speak you would be understood.

    2) Try answering my question. To repeat, what color (i.e., wavelength) is the fluorescence that you are trying to detect? The excitation wavelength is relatively unimportant.

    wavelength is at 400nm...
    actually i need a sensor for fluorescence...which is inexpensive..

    nw we are using uv led for fluorescence...

    Fluorescence, phosphorescence, chemiluminescence, bioluminescence, thermoluminescence, any other light are all the same as for detection. It depends on the wavelength. At 400 nm, the sensitivity of that detector is only 16% of what it is at 600 nm. It will still work.

    This comment,
    causes me to wonder whether you understand that. What is your question?

    And I'll say it again: If YOU can see the light, then so can the opt101. In fact it can "see" a bit more than you can. What more do you need to know?
