Application of Filters Basic Principle of Infrared Temperature Measurement Infrared temperature measurement is based on the relationship between the infrared radiation emitted by an object and its temperature. According to Planck’s blackbody radiation law, objects at different temperatures emit infrared radiation at different wavelengths. By detecting this radiation, the temperature of the object can be inferred.
Role of the 5.5 μm Infrared Filter
The 5.5 μm infrared filter is primarily used to selectively transmit infrared light at the wavelength of 5.5 μm while blocking other wavelengths. This wavelength range is of great significance in infrared temperature measurement because many materials exhibit strong radiation characteristics at this wavelength.
