DLPNIRNANOEVM: Info request about DLPNIRNANOEVM

Dakota Passage

Part Number: DLPNIRNANOEVM

I am working to measure and monitor industrial liquids (wastewater, sanitation/CIP, product quality). I am curious if the DLPNIRNANOEVM is a good fit for our use case. Is there some kind of plug and play development kit available? What is the lead time to acquire a sensor for us to test it?
I am also wondering if you can provide any information on the lifespan of the sensor, the error range of the sensors, as well as any information on sensor reading drift. Furthermore, is there also any information on how long it takes for the sensor to capture a full spectra and if it can be used for liquids inflow. In particular, I am curious if this eval board works well with determining compounds in milk and if it is okay to use this board outside of the testing temperature range (0 to 50C) stated in the user guide for this product.
Thank you very much.

    Hi,

    I want to thank you for your interest in DLP Technology!

    The DLPNIRNANOEVM itself is the development kit. From the product page on TI.com you can find the GUI software to interface with the EVM, as well as purchase one for evaluation. It appears that they are in stock so it should only be a week or so to receive.

    Regarding your other technical questions, let me talk with the team and ill see if we have any other resources besides what is on the product page

    Regards,

    Arthur Brown.

    Hello Dakota,

    The DLPNIRNano EVM has 10nm spectral resolution and 6000:1 SNR. For liquid sensing application, you may want to use the EVM with transmissive head.

    You can source transmissive head from third-party supplier  innospectra or Optecks.

    https://www.optecks.com/Portal/index.php/products-root/spectrometers/spectrometer-with-trasmissive-module

    It is very difficult to say if it is good fit for your application because over all performance will depend on the system setup, consistency of sample presentation, analytical tools/algorithm and target accuracy.

    You may also want to reach out some of our third-party  solution providers like AnalyzeIQ, Sagito

    https://www.analyzeiq.com/

    https://cloud.sagitto.com/

    They may be able to support tools and firmware.

    The NIRNanoEVM is an evaluation system to help our customer design and develop spectral sensing product based on DLP technology. The requested information  will depend on the overall system. If you are looking for product to use in production line then please reach out to Innosepctra and use finished product targeted for use in production.

     The EVM output could vary with humidity and temperature, especially SNR. It is not recommended to use it outside recommended temperature range.

    Please let us know if you have additional questions.

    regards,

    Vivek

    Thank you for your response. I would also like to know what the output looks like - how many readings would I get and how long would it take for the sensor to scan through the full spectrum. 

    Also, in the user guide it says that the USB application works with Windows 7 and 8. Does it now work with Windows 10 as well?

    Thank you,

    Dakota

    Hello Dakota,

    The EVM and GUI works with windows 10. 

    The scan time depend on the configuration and parameters. For example, the following is default configuration:

    Scan type -Column

    Spectral range : 900 nm to 1700 nm

    Digital resolution : 228

    The scan time (exposure time) for one scan is 0.217 second and there is overhead of start and end. It is around 1.4 sec. Typically, you want average multiple scans for consistent result.

    The following are scan time for above configuration:

    only 1 scan - 1.607 second

    average 2 scan - 1.824 ns

    average 6 scan - 2.691 second.

    There is diminishing return as your increase the number of scan to average. For your system set up , you may want to run an experiment to find optimum number for averaging.

    regards,

    Vivek
