NIR (>700nm) DMDs
Advance spectroscopy, optical networking and laser sintering with programmable near-infrared (NIR) light
Our near-infrared digital micromirror devices (DMDs) provide high-speed, programmable light modulation for spectroscopy, optical switching and laser sintering. Engineered for precise wavelength selection and robust performance across the NIR spectrum, these devices help engineers improve sensitivity, throughput and accuracy in compact, reliable instruments for a wide range of industrial applications.
Why choose TI near-infrared DMDs?
Programmable MEMS array
Hundreds of thousands of controllable pixels that are stable over temperature and lifetime to enable compact, robust designs.
High speed switching
Use fast switching speed to select wavelengths, attenuate signals, and perform scans at high speeds with programmable filters and multiplexing.
Extended wavelength support
These parts are designed to operate reliably at NIR (>700nm) wavelengths, and a wide range of light sources.

Design fast, accurate and small spectral scanners and spectrometers with DLP technology
All molecules have unique responses to different wavelengths of light. Spectroscopy uses these unique responses to identify and characterize materials.
When material is scanned, the spectrum of light is dispersed onto the DMD using a diffraction grating or prism. Specific wavelengths can then be directed into a single-element detector. This enables chemical analysis with higher performance and smaller form factors at lower costs.

DLP technology enables fast handheld spectral scanners for monitoring and testing materials
All molecules have unique responses to different wavelengths of light. Spectroscopy uses these unique responses to identify and characterize materials.
Programmable DLP chips can quickly scan and monitor specific wavelengths with a single-element detector. The scanners can intelligently monitor for changes like contamination, ripeness, and identify variations. This enables material analysis with higher performance and smaller form factors at lower costs.
