Hi!,
Anyone have worked with a NIR pocket equipment?. I'd like to see comments about SCIO NIR Scan vs DLP Nano Texas Instruments.
Here is the info:
1. DLP® NIRscan™ Nano Evaluation Module

2. SCIO Development Toolkit - SCiO Sensor + Development License

Thanks!.
HI - sorry it took so long to answer and I hope you are still interested. We are using both devices and in short, the NIRscan Nano is a real spectrometer that delivers data that I trust in the true NIR region (900-1700 nm). It is based on an InGaAs detector It delivers good S/N in reasonable measurement times. And the raw data is there for you to look at.
The Scio on the other hand uses a Si detector (which dies at 1000nm) so it does not cover the real NIR region. According to a teardown on sparkfun, it has 12 filters. How with 12 filters over the 700-1050 region do you get 1nm data point spacing? Obviously they are interpolating something. Personally I don't want someone messing with my data before I see it. And because they mess with the data calculating S/N isn't possible.
IN my opinion, the NIRscan Nano is a real spectrometer that works. The Scio is a toy that is going to give spectroscopy a bad name.
I'd echo Ellen's words here. We tried SCIO as well and it didn't measure up to anything you'd want to do seriously. There is lot of hype around these consumer "pocket" NIR sensors and needs to evaluate carefully while choosing a sensor for industrial use.
