Monospectral

Part of speech: adjective

Definitions

1. Relating to or involving a single spectrum or wavelength of light; characterized by emission, absorption, or analysis within one specific spectral band; pertaining to methods or devices that utilize only one spectral range
2. Pertaining to phenomena or techniques that use a solitary spectral component, such as monochromatic light sources or sensors tuned to a particular wavelength; involving narrowly focused spectral properties; describing instruments operating within a single spectral band
3. Describing light or systems confined to one spectral frequency or color; involving measurement, observation, or application restricted to a unique spectral interval; used to define technologies or experiments centered on a single wavelength domain

Etymology: "Monospectral" is a plain compound built from two parts: "mono-", from Greek "monos" meaning "single" or "alone", and "spectral", the adjective from "spectrum." The spectrum itself is a Latin word, "spectrum," meaning "appearance" or "image," from "specere," to look at. Isaac Newton's experiments with prisms in the 1600s gave the word its optical sense of the band of colors light splits into, and "spectral" followed from that sense of the rainbow-like band. Putting "mono-" in front produces a word meaning "of a single spectrum," which is why the term is used for light, or for instruments and experiments, restricted to one wavelength or color range. The formation follows the same pattern as older compounds such as "monochromatic," which is built from the same Greek prefix plus a word for color.

Synonyms: single-spectrum, monochromatic, unicolor, uniform-spectrum
