Portable Spectroscopy Solution - DLP NIRscan EVM

A spectrometer collects the light that is either reflected from - or transmitted through -- the sample, and breaks it down into its constituent wavelengths with a diffraction grating. This allows a detector - either an array or a single element - to measure light intensity by wavelength, thus establishing the material's signature. The problem is that array-type detectors are expensive. Single-element detectors are cheaper, but fragile; they require the grating to be rotated so different wavelengths can be sequentially detected.

TI's battery operated "DLP NIRscan™ Nano Evaluation Module" incorporates a digital micromirror in the optical path to steer light, a diffraction grating, and a single element detector. The module can be linked to cloud databases over Bluetooth® low energy for real-time analysis of the sample's signature. Try it for yourself. What will you scan?
