Stay Tuned: Photonic Filters Color Your World
Mar 1, 1997 — Spectral information enhances our knowledge of astronomy, chemistry, metallurgy, and meteorology, and it contributes to applications in photonics, communications and medical instrumentation. Different specialties may use one of many spectral selection methods, as each has particular advantages. Some applications may require high transmission and a broad field of view for 2-D imaging, while others need narrow spectral resolution or a broad tuning range. Size, cost, aperture, stability, and...
