ThermTec thermal imaging cameras receive and display infrared radiation emitted by objects. All objects with temperature emit infrared radiation. Thermal imaging cameras receive infrared radiation emitted by objects and display temperature distribution on measured object surfaces through color images, identifying and monitoring anomalies based on subtle temperature differences. They are also known as thermal cameras.

Natural light consists of light waves with different wavelengths. The range visible to the human eye is approximately 390-780nm. Electromagnetic waves shorter than 390nm and longer than 780nm cannot be perceived by the human eye. Among these, electromagnetic waves with wavelengths shorter than 390nm are located outside the violet end of the visible light spectrum and are called ultraviolet rays. In comparison, electromagnetic waves longer than 780nm are located outside the red end of the visible light spectrum and are called infrared rays, with wavelengths ranging from 780nm to 1mm. Infrared radiation is electromagnetic waves with wavelengths between microwaves and visible light, sharing properties with radio waves and visible light. In nature, all objects with temperatures above absolute zero (-273.15°C) continuously emit infrared radiation, known as thermal radiation. Infrared thermal radiation technology uses micro thermal radiation detectors, optical imaging objective lenses, and opto-mechanical scanning systems to receive infrared radiation signals from measurement targets. After spectral filtering and spatial filtering, the focused infrared radiation energy distribution pattern is reflected onto the photosensitive elements of the infrared detector. The infrared thermal image of the measurement target is scanned and focused by a unit or spectral detectors. The detector then converts the infrared radiation energy into electrical signals, which are amplified and processed before being converted into standard video signals for display on TV screens or monitors.
