TIDA-00155: Question on direct coupling / connector to product interface: is it fiber optic, what is the connector from the casing to the product being quantified? (IE how would I attach a diffuse reflectance probe)

Part Number: TIDA-00155

I am interested in the DLP NIR Scan EVM. I am working with a company who specializes in product interfaces (a physical optical interface; NOT internet connectivity and user interfaces) and probes. From what we have seen, this device does not have an optical window / probe built into it already. 

What kind of connector is there between the module and the product being quantified? Is it a direct coupling using fiber optics or is there a probe built into the product already? If I wanted to use the product with a diffuse reflectance probe, how would we go about attaching that probe to the device to run analysis?

  • Hello Philippe,

    I'm actually asking about the tabletop DLP NIR Scan EVM with the 30,000:1 transmissive head (not the nano with the 6000:1 reflective head). On the tabletop model, what is the input? I need to know what type of port connects the device to the front end / probe. If the coupling isn't a direct fiber optic, what is it?

    When you know about the probe, let me know.

    Also, the link to Young Green is dead and said the server was not found. Additionally, the user guide link also said "sorry, we couldn't find the page you were looking for.

  • Michael,

    I made the mistake of interpreting your query as being related to the NIR scan Nano. It appears this is actually regarding the 4500 NIR EVM. I will delete my previous post so as to not confuse fellow users.

    First off, here is the 4500 NIR EVM User's Guide in case you don't have it:
    www.ti.com/.../dlpu016b.pdf

    Specifically, you should start by referring to section 1.2.1 and 1.2.2 in "DLP NIRscan Electronics." Are you asking about how the optical engine connects to the NIRscan electronics or how the sample is provided (which is in a tube)?

  • Hi Philippe,

    Thanks for the response! I'm asking how the sample is provided. How do you preform analysis on a sample (are there sample tubes provided with the product)? My follow up question would be how do you go about changing the product interface? 

    I want to connect a diffuse reflectance probe to the device instead of using the sample holder provided. Is there a way to connect a probe to the lamp through some sort of input or connector? Also, is there a direct coupling between the optical window / sample holder and a fiber optic? If is is not a fiber optic, what type of connector is there? 

  • Michael,

    Samples are provided via cuvette, which are not supplied by TI. I would check out, for instance, Thor Labs for this need:
    www.thorlabs.com/index.cfm

    As for your other question, the system does not use a direct coupling, as the lamp is simply used to illuminate the sample. Based on this previous E2E thread, it does not look like this sort of modification is formally supported:
    e2e.ti.com/.../513347

    You may need to contact an external design house for assistance with this. I apologize for the inconvenience.

    Best Regards,
