Introduction
The DLP® NIRscan Nano™ EVM is a complete evaluation module to design a high performance,
affordable near-infrared portable spectrometer. This flexible tool contains everything a designer needs to
start developing a DLP-based spectrometer right out of the box. DLP technology enables handheld
spectral analyzers for use in the food, pharmaceutical, oil and gas, medical, security, and other emerging
industries to deliver lab performance levels in the field. The EVM contains the DLP2010NIR digital
micromirror device, DLPC150 digital controller, and DLPA2005 integrated power management
components. This technology brings together a set of components providing an efficient and compelling
spectroscopy system solution for:
•
Portable process analyzers
•
Ultra-mobile spectrometer
The new DLP2010NIR DMD is optimized for operation at wavelengths between 700 and 2500 nm. The
DLP NIRscan Nano EVM is one possible implementation of this new DLP technology, operating from 900
to 1700 nm.
