Thermography or thermal imaging, refers to the process of recording the emission or existence of thermal or infrared radiation (heat), by employing the use of a thermal imaging device or infrared camera, sometimes referred to as an "IR". Although thermal imaging can be used in the daylight, thermography allows one to "see" in the dark as it does not rely of the reflectance of light within the "visible" range of the Electromagnetic spectrum in order to record imagery. All objects at temperatures above Absolute Zero ( 0 K or -273.15 °C) emit some sort of thermal radiation, many within the infrared portion of the Electromagnetic spectrum. Thermography refers to the wavelengths within the spectrum in units of nanometers, micrometers, or microns. The commonly referred to ranges within the spectrum are gamma rays, x-rays, uv rays, visible, infrared (IR), microwave, and radio. Some objects that are very hot (such as the Sun) emit thermal radiation viewable within multiple parts of the EM spectrum such as the "visible", the "ultraviolet" (UV) and the "infrared" areas.
Products & Services
Infrared Sources are optoelectronic devices that emit infrared light.
Focal plane arrays (FPA) are detectors consisting of a linear or two-dimensional matrix of individual detector elements, typically used at the focus of an imaging system.
Thermal imagers detect heat patterns in the infrared wavelength (1 micron to 100 micron) spectrum.
UV sensors are designed to measure the power or intensity of incident ultraviolet (UV) radiation.
Spectrometers are analytical instruments which disperse an emission (such as particles or radiation) according to some property of the emission (such as mass or energy) in order to measure the amount of the dispersion. This product area includes visible, infrared (IR), ultraviolet (UV), atomic absorption (AA), optical emission (OE), Raman, X-ray fluorescence (XRF) and mass spectrometers. Specific search forms are also available.
