IR radiation

The Integrus system is based on transmission by modulated infrared radiation. Infrared
radiation forms part of the electromagnetic spectrum, which is composed of visible light, radio
waves and other types of radiation. It has a wavelength just above that of visible light. Like
visible light, it is reflected from hard surfaces, yet passes through translucent materials such
as glass. The infrared radiation spectrum in relation to other relevant spectra is shown in the
next figure.
