SCOPE —a Famous Trails device with one ocular system.
SPECTRAL RESPONSE —the numeric range of wavelengths in the phototonic spectrum amplifiable by a Famous Trails device. While the human eye can see from 400nm to 750nm, a Famous Trails system can pick up and amplify wavelengths up to 900nm and project an image of the viewed object onto its phosphor screen.
SPECTRUM —see phototonic spectrum
WAVELENGTH—the distance covered by one cycle of a wave. Electromagnetic energy is transmitted in sinusoidal waves. Nanometers (nm) and Micrometers (mn) are units of measure in the photonic spectrum.
