Miniature spectrometers revolutionized the spectroscopy market more than 15 years ago and became a key factor in the creation and steady growth of the photonics field. Today these spectrometers are becoming an important part of the new market of field-deployable analytical instruments used for materials identification based on Raman spectroscopy. Just as before, these spectrometric photonic engines are key factors on reducing the cost and improving the flexibility of applications of a traditionally expensive and rigid vibrational spectroscopy method. Raman spectroscopy is becoming an affordable tool used for applications ranging from homeland security to green energy research and development, either at a laboratory, a crime scene, or a biodiesel manufacturing facility.
