An Infrared thermometer is an apparatus that is used for measuring temperature employing the concept of blackbody radiation that is emitted from a body. The Infrared thermometer is also identified as laser thermometer many a times if a laser is required for aiming the thermometer. It is required to measure temperature from a distance without any contact. If the infrared energy that is being emitted by a body is known, then the temperature of the body can be easily determined with the help of an infrared thermometer. The basic structure of an infrared thermometer consists of a lens that focuses on the infrared energy which hits the detector when the energy is converted to an electrical signal that can be displayed in units of temperature after being compensated for ambient temperature variation.

This configuration of the infrared thermometer is such that it helps in the measurement of temperature even from a distance without being in physical contact with the concerned object.
The infrared thermometer comes of a great use when the probe type sensors or thermocouples do not provide accurate data for some reasons or do not function at all. The infrared thermometer finds use when the temperature of a moving object in an electromagnetic field is to be measured. It is also required to measure the temperature of an object in vacuum. It is very fast and convenient and that is why it is used in applications which need fast results. One of the most interesting things about Infrared thermometer is that it is used for a wide range of functions related to temperature monitoring. Some of them include cloud detection for operation of remote telescope, serving as hot spots outlets, for control and calibration and checking hot spots. It is also required during the research and development as well as in the manufacture of situations of quality control.
Today in the market a number of devices for measuring infrared temperature have come up with improved technology. These are not only more flexible but also portable and can be used for purposes which demand more time duration. The distance-to-spot ratio or the D:S ratio of the object and the diameter of the area to be measured. For example if the D:S ratio shows 13:1, it means that the object is placed 12 inches away and the are is 1inch in diameter. A non-adjustable thermometer finds the right use in measuring a shiny surface temperature on which a non shiny paint or tape is applied. Spot Infrared Thermometer which is also known as Infrared Pyrometer is the commonest type of infrared thermometer. Some of the equipments that are related to the infrared thermometers are Infrared Line Scanning Systems and Infrared Camera. The Infrared Line Scanning Systems are used for measuring the cement kiln shell temperature. The Infrared Camera is used for measuring the temperatures at many points over a comparatively large area that generates a 2 D image, where the temperature is represented by each pixel. Thus it can be said that the infrared is very useful.
