The IR, or infrared radiation is electromagnetic radiation with wavelengths shorter than microwaves and terahertz radiation from the visible light but long. Infrared technology, which means that down the name adopted in Latin and consist of infra red English word meaning red and comes with the six-meaning red. Color red is the longest wavelength of visible light. The wavelength of the infrared radiation between 750 nano meters and 1 micrometer. In the normal human body temperature is around 10 micrometers made radiation.
Objects emit infrared radiation in wide spectra, but only because they can detect sensors for specific bandwidths are usually referred to the specific infrared bands. Therefore infrared band is divided into smaller subbands.
International Commission on Illumination (CIE) separating infrared radiation has
proposed the following tape.
IR-A: 700 nm-1400 nm
IR-B: 1400 nm to 3000 nm
IR-C: 3000 nm-1 mm
A partitioning format commonly used are as follows:
Near-infrared (NIR, IR-A DIN): 0.75-1.4 .mu.M between wavelengths. Because of the low amount of losses it is generally used in fiber optic communications. Night vision equipment is generally used at those wavelengths.
Redwell heats only the walls unlike conventional heaters warm the air. Walls are stored much longer than air and gives back slowly to room temperature environments. Therefore, it becomes impossible to disperse the walls and moisture stay dry. Another advantage is that the airflow does not pass to the movement of the powder is.
