This near-infrared (NIR) spectrometer reference design utilizes Texas Instruments' DLP technology in conjunction with a single-element InGaAs detector to deliver high performance measurements in a portable form factor that is more affordable than expensive InGaAs array detector or fragile rotating grating architectures. NIR spectrometers are commonly used to analyze organic-based liquids and solids for applications including food, agriculture, pharmaceuticals, petrochemicals, and plastics to name a few. Combined with a powerful Sitara™ embedded Processor and analog signal chain components, developers are now able to bring the power of high-end laboratory spectrometers to the field and manufacturing line.
- Acquire spectrum transmittance data across a 1350 to 2450 nm wavelength range in less than 1 second with >30,000:1 signal-to-noise ratio (SNR)
- Single element InGaAs detector design delivers high light throughput combined with a more affordable price point compared to InGaAs arrays
- Programmable wavelength filtering enables constant SNR scans, on-the-fly wavelength and resolution adjustment, and chemometric algorithms
- High resolution spectrum acquisition with up 1824 data points
- Linux operating system and integrated web server based on the Beagle Bone Black open source architecture supports flexible connectivity through USB, Ethernet, WiFi, or Bluetooth
- Robust MEMS-based design eliminates moving gratings or mirrors for portable equipment
