It cools and dehumidifies campers, vans, and motorhomes up to 6 meters without needing a 220V connection or a combustion backup generator, significantly reducing power consumption and CO2 emissions compared to 220V solutions. Equipped with Bluetooth and Wi-Fi connectivity, this model allows remote control.

Infrared wavelengthrange in nm

The 12V mobile air conditioner revolution: Indel B’s range of OFF air conditioning systems is synonymous with innovation, efficiency and practicality.

The human eye is a natural wonder, the result of millions of years of evolutionary tinkering, and... remarkably limiting. Our eyes can only see a small sliver of the electromagnetic spectrum, so to see anything else requires relying on technology that can glimpse these “invisible” wavelengths.

Plein-Aircon 12V with Ringlight Diffuser offers improved air distribution and a built-in ringlight with white and blue light options, perfect for night-time travel.

Infrared light wavelengthand frequency

One of the most useful of these wavelengths is infrared, the waves of which stretches between 760 nanometers to 100,000 nanometers (the name comes from the fact that it’s just longer than the color red, the longest wavelength in the visible spectrum). Infrared is used in all sorts of applications—especially imaging—and being able to manipulate this wavelength can produce better results.

To test this new device and see if it could “squeeze” infrared light to a useful degree—an idea that had insofar only been theoretical, according to the researchers—the team turned to the Advanced Light Source at the Lawrence Berkeley National Laboratory. This research facility runs an infrared program capable of probing materials at micro- and nano-scales. The team performed synchrotron near-field spectroscopy on the thin strontium titanate film, and what was once theoretical became very much practical.

Liu and his colleagues said that this breakthrough could lead to a whole new generation of infrared imaging technologies and thermal management devices. “Imagine,” Liu said, “being able to design computer chips that could use these materials to shed heat by converting it into infrared light.”

That’s why scientists from North Carolina State University worked to successfully “squeeze” infrared light to 10 percent of its wavelength while maintaining its frequency. The researchers achieved this breakthrough by using a special class of oxide membranes rather than bulk crystals, which can traditionally only barely squeeze infrared light. The results of this study were published earlier this month in the journal Nature Communications.

According to the statement, the researchers made use of “transition metal perovskite materials” in the study. Using pulsed laser deposition—which involves a powerful pulse laser beam in a vacuum chamber—the researchers grew a 100-nanometer-thick membrane made of an oxide of strontium and titanium called strontium titanate (SrTiO3). Once completed with very few flaws, the films were removed from that substrate and placed on a silicon substrate.

“We’ve demonstrated that we can confine infrared light to 10% of its wavelength while maintaining its frequency—meaning that the amount of time that it takes for a wavelength to cycle is the same, but the distance between the peaks of the wave is much closer together,” Yin Liu, a co-author of the study, said in a press statement. “Bulk crystal techniques confine infrared light to around 97% of its wavelength.”

To understand what happened next requires a brief foray into Particle Physics 101. Photons are particles of light and the fundamental unit of the electromagnetic spectrum. Phonons, on the other hand, are “a fancy word for a particle of heat” (according to MIT), but can also be thought of as sound energy. Both photons and phonons deal in the realm of excitations and vibrations—however, when an infrared photon is coupled with an optical phonon (a.k.a. a phonon that can emit or absorb light), then it forms a quasi-particle called a “phonon polariton.” It’s these polaritons that do the squeezing.

“Theoretical papers proposed the idea that transition metal perovskite oxide membranes would allow phonon polaritons to confine infrared light,” Liu said. “And our work now demonstrates that the phonon polaritons do confine the photons, and also keep the photons from extending beyond the surface of the material.”
