It is a high power IR transmitter driving two IR LEDs through a Darlington ... Q_ (Pin 11) is the complimentary output of IC1 which is used to connect the indicator LED which flashes in sympathy with ...

That is, if you read that a high power LED emits no UV or IR and that any heat is created only in the PN junction and then transferred to a heat sink. Okay on the UV part; but the IR part? Read on.

In a move straight out of a sci-fi movie, scientists have created wearable infrared contact lenses that allow you to see in ...

Now, scientists have found that in some cases green laser pointers emit high levels ... twice its rated power level of light -- but at invisible and potentially dangerous infrared wavelengths ...

Nanoparticle-infused contact lenses can transform infrared radiation into different colours of visible light, potentially ...

Engineered with infrared-converting nanoparticles, these smart contact lenses allow users to see heat signatures with the naked eye.

To overcome this challenge, the researchers optimized a method called distributed laser charging, which has recently gained more attention for this application because it provides safe high-power ...
