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.
