The most common infrared thermometer is the spot infrared pyrometer or infrared pyrometer, which measures the temperature at a spot on a surface (actually a relatively small area determined by the D:S ratio). These usually project a visible red dot onto the center of the area being measured that identifies the spot being measured, but plays no ...

Example of hand held electric heat gun Commercial heat gun kit Flame heat gun for shrinkwrapping helicopter. A heat gun is a device used to emit a stream of hot air, usually at temperatures between 100 and 550 °C (373 and 823 K; 212 and 1,022 °F), with some hotter models running around 760 °C (1,030 K; 1,400 °F), which can be held by hand.

A household infrared electric heater. An infrared heater or heat lamp is a heating appliance containing a high-temperature emitter that transfers energy to a cooler object through electromagnetic radiation. Depending on the temperature of the emitter, the wavelength of the peak of the infrared radiation ranges from 750 nm to 1 mm. No contact or ...
The Seattle Fire Department acquired its first thermal imaging camera in 1997, for a cost of $16,000. [ 22 ] In 2000, the Los Angeles Times called the thermal imaging camera "[p]erhaps the best advance in fire equipment in the last 25 years—and the most expensive". [ 23 ]
That is, if the contact temperature of a thermally uniform black body radiator were 50 °C (122 °F), it would emit the characteristic black-body radiation of 50 °C (122 °F). An ordinary object emits less infrared radiation than a theoretical black body. In other words, the ratio of the actual emission to the maximum theoretical emission is ...
The amount of cadmium (Cd) in the alloy can be chosen so as to tune the optical absorption of the material to the desired infrared wavelength. CdTe is a semiconductor with a bandgap of approximately 1.5 eV at room temperature. HgTe is a semimetal, which means that its bandgap energy is zero. Mixing these two substances allows one to obtain any ...
