NASA researchers identify optimal infrared wavelength for detecting carbon dioxide and methane on exoplanets, guiding the Habitable Worlds Observatory’s design and sensor specifications.

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new research, I explore a different possibility: Rather than postulating new ...

Punch-drunk syndrome, boxer’s madness, chronic traumatic encephalopathy (CTE). The name has changed over the years, but the cause is clear: repeated impacts can affect long-term brain health, with ...

This all-purpose presence sensor is a master at monitoring indoor activity and linking it to smart home features you already use. Tyler has worked on, lived with and tested all types of smart home and ...

Aqara has announced the Spatial Multi-Sensor FP400, a new presence sensor that it says is precise enough to suss out whether you’re sitting, standing, or lying down. The FP400 builds on several past ...

Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...

Infrared devices have become increasingly popular in recent years and can be found in many gyms to reduce muscle pain and inflammation. There are also many at-home infrared light devices for muscle ...

Extending its portfolio of image sensors for automotive applications, Sony Semiconductor Solutions Corp. has announced the upcoming release of its new 5-megapixel (MP) IMX775 CMOS RGB-IR image sensor ...

When it comes to the best infrared hair straighteners and other hairstyling tools, there’s a lot of buzz around what exactly this so-called “revolutionary” infrared technology is. And as with many ...

The visible light spectrum that humans perceive spans only a small portion of the electromagnetic spectrum — roughly 430 to 750 THz, corresponding to wavelengths of ~400-700 nm. Just beyond this range ...

Whether you're searing steaks in a cast-iron skillet, calibrating a pizza oven, or checking the temperature on HVAC equipment, a reliable infrared thermometer is a necessity not only for accuracy but ...

Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light. Lenses are the most widely used ...
