DLP® NIRscan™ Evaluation Module


Order now



The DLP NIRscan is a complete evaluation module (EVM) to design a high performance, affordable near-infrared spectrometer.  This flexible tool contains everything a designer needs to start developing a DLP-based spectrometer right out of the box.  The EVM features the DLP 0.45 WXGA NIR chipset - the first ever DLP chipset optimized for use with near-infrared (NIR) light.  With DLP technology, spectrometers for use in the food, pharmaceutical, oil/gas and other emerging industries will be able to deliver lab performance levels in the factory and the field.
