Infrared Technology
The optical system of an infrared sensor collects the infrared energy from a circular measurement spot and focuses it on the detector. Optical resolution is defined by the ratio of the distance from the instrument to the object, compared to the size of the spot being measured (D:S ratio). The larger the ratio number the better the instrument's resolution, and the smaller the spot size that can be measured from greater distance.
Infrared Technology
Emissivity is the measure of an object's ability to emit infrared energy. Emitted energy indicates the temperature of the object. Emissivity can have a value from 0 (shiny mirror) to 1.0 (blackbody). Most organic, painted, or oxidized surfaces have emissivity values close to 0.95. The majority of our IR sensors have an adjustable emissivity feature to ensure accuracy when measuring other materials, such as shiny metals.

Infrared Technology
Temperature plays an important role as an indicator of the condition of a product or piece of machinery, both in manufacturing and in quality control. Downtimes are decreased since the manufacturing processes can proceed without interruption and under optimal conditions. Infrared technology has been utilized successfully in industry for decades, but new developments have reduced costs, increased reliability, and resulted in smaller, noncontact infrared measurement devices.
