Read our contributed article in the April 2021 issue of Focus Laser World about the advances in DMD-based spectrometers and how they can benefit industry and medicine.

“Compact near-infrared spectrometers based on digital micromirror devices (DMDs) can be lower in cost than diode-array spectrometers while maintaining high stability.

Ongoing developments in industries such as precision agriculture and healthcare point-of-care (POC) testing have increased the demand for compact, low-cost, and ruggedized spectral analyzers. For applications using the near-infrared (near-IR) spectrum from 900 to 2500 nm, this is particularly challenging since spectrometers for this wavelength range tend to be much more expensive than devices for the visible wavelength range. This article will show how advances in spectrometers based on digital micromirror devices (DMDs) can address cost, compactness, and stability issues.”
