Using Quantum Optics2 Technology, Spectrum Response causes the treated materials of the fly to absorb radiation in the ultraviolet region of the electromagnetic spectrum, and re-emit light in the ultraviolet and visible regions of the spectrum; imitating the hyperspectral light emittance and signature of a living aquatic organism. Ongoing research shows that many predator fish species can detect wavelengths of both visible light and ultraviolet light.
Achieving optical gain, the treated fly now emits more visible light than it absorbs, appearing colorful and radiant. This unique energy conversion technology provides pronounced and sustained visibility of the fly and is profoundly effective in aquatic environments rich in ultraviolet light and deficient in visible light.
Shorter wavelengths of light penetrate the water more effectively and are thus seen from farther distances by game fish. Spectrum Response causes the fly to radiate more light in the shorter wavelengths causing the fly to be more visible from farther distances by game fish.
