Spectroscopy

Spectroscopy is the measurement of a quantity as a function of either wavelength or frequency. The interaction between a wavelength of light and a sample produces information that describes the chemical composition of that sample.

Different wavelengths travel different distances and penetrate different depths. As a result, spectroscopy can be applied to any variety of sub-surface measurements across a multitude of fields. Some examples of industries and types of analysis are listed below:

Medical:	blood and tissue analysis
Natural Resources:	oil and mineral exploration
Food:	ingredient authentication
Pharmaceutical:	raw chemical purity detection
Environmental:	air/water quality
Agricultural:	detecting ripeness levels

Any spectroscopic system requires the ability to select the wavelength of light. The Digital Micromirror Device (DMD) at the heart of DLP® technology allows the dynamic selection of various wavelengths of light through millions of independently controlled bi-state mirrors. This means that spectroscopic measurement systems no longer need to be designed with a fixed wavelength input. Instead, the DMD chip can help achieve a ‘tunable’ spectrometer that allows measurement of different materials using different wavelengths of light using the same spectrometer system. As a result, DLP® technology is gaining attention in various spectroscopy segments including molecular and atomic spectroscopy.
