Unispectral

Part of speech: adjective

Definitions

1. Relating to or involving a single band of the electromagnetic spectrum; pertaining to data, analysis, or imagery captured or processed within one specific wavelength range; denoting phenomena or devices that operate using one spectral component
2. Describing properties or measurements confined to one spectral region; concerning images or signals recorded exclusively at one wavelength; applicable to systems or methods utilizing a single spectral interval
3. Characterizing observations or instruments that focus on a solitary spectral band; relating to spectral data limited to a single frequency range; indicating processes or techniques that employ only one part of the spectrum

Etymology: "Unispectral" is a transparent compound. The prefix "uni-" comes from Latin "unus," meaning "one," and "spectral" comes from "spectrum," a Latin word for "appearance" or "image," derived from "specere," "to look." The optical sense of "spectrum" as a band of colours was given to the word by Isaac Newton, who used it for the rainbow of light that appears when sunlight passes through a prism. Put together, the parts mean "of one spectral band." The word is a technical formation from classical elements, not an ancient word, and it describes measurements, images or instruments limited to a single wavelength range.

Synonyms: monochromatic, single-spectrum
