First, the sample is illuminated with infrared light. After the light interacts with the sample, the resulting wavelengths are ‘upconverted’ from low-energy infrared to high-energy near ...

This improved infrared detector is specifically intended for use with commercial IR remote control handsets. This little circuit is useful for quick go/no-go testing of just about any remote control ...

The light strip is called the LIFX Z and will sell for $89.99. It’s 2-meters long and includes eight “zones” per meter that can be programmed to different colors. One-meter extensions are ...

But the circuit in the figure shows an infrared close-object alert system built around two popular and less expensive integrated circuits: the LM555 timer and CD4060 CMOS, 14-stage, ripplecarrying ...

This recycling of infrared light pushed the device’s efficiency to 25.4 per cent – that is on par with common LEDs, but more than a tenfold improvement over conventional light bulbs.
