DLP® NIRscan™ VS DLP® LightCrafter™ 4500

Other Parts Discussed in Thread: DLP4500, DLPC350, DLP4500NIR

Hi,

 I read in document that both are having the same DLP:

TI NIRscan EVM has many similarites with the LightCrafter 4500 module
– NIRscan uses the DLP4500 DMD in structured light mode to provide a cheap, efficient
spectroscopy solution

I found that the price difference is between the two is around 5 times. Why it is so?. 

 Would like to know what do we get extra by paying this extra amount. 

We would like to design portable spectroscopy solutions, and looking for a cheaper solution for prototyping.  

 Thanks and regards,

Heshsham

    Hello Heshsham,

    There are a few differences between the LightCrafter 4500 and NIRscan which factor into the higher cost. First let me describe the LightCrafter 4500. The LightCrafter 4500 EVM features the DLPC350 chipset with the DLP4500 specified for wavelengths between 420 and 700nm. The kit includes a controller board and an RGB light engine with 150L output.

    The NIRscan features the DLPC350 chipset with the DLP4500NIR specified for 700-2500nm. The kit includes the several additional pieces in addition to the control circuitry required for the DLP chipset such as the Sitara processor for a fully operational embedded spectroscopy solution, a thermally cooled single point InGaAS detector, and ADC circuitry. The primary reason for the higher cost is the spectral engine which enables spectral scanning in the wavelength range of 1350-2450nm. The spectral engine accounts the majority of the cost of the EVM.

    In summary, here are the extra's in the NIRscan as compared to the LightCrafter 4500
    - Spectral Optical Engine for 1350nm to 2450nm scanning with the DLP4500NIR DMD
    - Sitara processor for embedded spectroscopy solution
    - Themally cooled single point InGaAs detector

    The LightCrafter only includes the basics needed for operating the DLPC350 chipset, but the NIRscan is a complete application specific design. Designing a spectral engines is not only expensive and can take a very long time, so if you're looking for a quick way to evaluate DLP technology for spectroscopy I recommend the NIRscan. If you only need the controller board for the DMD and already have a spectral engine, software, detector, etc. I recommend the LightCrafter 4500.

    Let me know if you have any more questions!

    Best regards,

    Dear Blair,

    Thanks for your detailed explanation.
    Let me educate myself by reading datasheets, and then will get back to you.

    Dear Blair.

    Project has to start now.
    Would like to know if there is any new offering in NIR.

    Thanks ,

    As far as NIRscan concerned there is anything new released; you may want to take a look at the firmware update if any on the TI website for NIRscan.

    We have released smaller form factor EVM you can have a look at it http://www.ti.com/tool/dlpnirnanoevm?keyMatch=NIRscan%20nano%20evm&tisearch=Search-EN-Everything

    Dear sanjeev,

    Thanks for your quick reply.

    Can you highlight the difference between nano version and its parent.

    Our application is basically on food content.

    Rgrds,

    I see that niether arrow nor avnet is selling this product. So I would like to know about alternate support in India during the product development.

    Hello Heshsham,

    There are many differences between the NIRscan and the NIRscan Nano including their size, wavelength range, and signal-to-noise ratio. Check out their individual pages for more information and let us know if you have any questions.

    I am going to move this thread to a forum where we cover NIRscan topics, perhaps your question about finding an India supplier can be addressed there.

    Best regards,
