Near infrared DLP device reduces BoM for spectroscopy

The DLP4500NIR is the first DLP device optimized for use with near infrared (NIR) light. Together, the DLP4500NIR and the DLP NIRscan evaluation module suit transmittance and reflective spectroscopy for use in the food, pharmaceutical, oil and gas, and emerging industries that will be able to deliver lab-quality performance out in the field and on the manufacturing line. When paired with a single element detector, the DLP4500NIR allows engineers to replace expensive linear detector arrays to create high-performance spectrometer designs, while reducing the typical bill of materials. Optimized for use with 700- to 2500-nm light, it can be programmed to select and attenuate multiple wavelengths at speeds up to 4 kHz. The DLP technology architecture also enables signal-to-noise ratios greater than 30,000:1 over a set measurement period.

Each of the micromirrors on the near IR device can be controlled to produce set patterns, with users able to further refine spectral resolution and wavelength ranges, adjust integration time, and equalize light throughput. As a result, users can employ adaptive scanning techniques to optimize material analysis on the fly for a broader range of substances using a single system. The near IR device can also be used in other applications, including single-pixel cameras, laser marking and microscopy.
