Why is it called Focused Infrared and how is it different from normal IR?

PDR's infrared technology is not like any other IR system on the market. PDR's  IR technology is different, we use short wave IR and project the light energy through a lens unit to create a Visible Focused IR Beam. It is called Focused IR because we are focusing the IR energy through the PDR lens unit and therefore creating a focusable and size adjustable heating spot/area to perform rework. Other competitive IR technologies use Medium wave IR for the top heater, which is what PDR uses to preheat the PCB from underneath.  Standard Non-visible/Non-Focusable IR Systems usually look like a standard heating panel and are not visible to the eye leading to guesswork as to what is actually being heated.
