An infrared pen is only a pen shaped holder for someone to apply infrared light (heat) the ease
infrared waves and infrared radiation both are same
Infrared radiation, infrared, heat radiation.

Infrared radiation has longer wavelengths.
infrared radiation is invisible to humans
The principle is the infrared light source that is inside. It takes all of the colors in the spectrum and uses them to make the light work.
You can burn the surface of an LCD or plasma display with a laser that is either high intensity (Over 5 mw) or had its infrared filter removed. But then you can burn the surface of most plastics with a 50 mw laser pen.
No they are not. The difference is the light. Laser pens will have the red shining light while the infrared pens won't have any visible light. The only way you will be able to tell if it's working (the infrared pen) is you have to test it against either a wiimote or camera lens for more information visit http://infraredpens.com/

The infrared quartz heaters have the infrared emitters and they emit infrared rays continuously to heat the heater in the instrument. The heat is generated and infrared emission stops.

Depending on what kind of infrared heater you want, there are many retailers that carry them. Home Depot has portable infrared heaters and infrared ceiling heaters. Safer Wholesale sells portable infrared heaters and patio infrared heaters.
Infrared radiation has longer wavelengths.

Infrared Rays (IR) originate from the sun :)
Infrared radiation is an electromagnetic wave.
