Lämpökuvauskamera

Lämpökuvauskamera, also known as a thermal imaging camera, is a device that detects and captures infrared radiation, which is invisible to the human eye. This radiation is emitted by all objects with a temperature above absolute zero. The camera converts this infrared energy into a visual image, often displayed in a spectrum of colors, where different colors represent different temperature levels. Warmer areas typically appear as brighter or redder colors, while cooler areas are depicted as darker or bluer colors.

These cameras have a wide range of applications. In building inspections, they can identify areas of heat loss or gain, pinpoint insulation deficiencies, and detect moisture problems. In the industrial sector, they are used for predictive maintenance, monitoring the temperature of machinery to prevent failures, and inspecting electrical systems for overheating components. For public safety and security, thermal cameras can detect people or animals in low-visibility conditions, such as at night or in smoke. They are also utilized in the medical field for diagnostic purposes and in scientific research for observing temperature variations.

The core component of a thermal imaging camera is its infrared detector, which is sensitive to the specific wavelengths of infrared light. Different types of detectors exist, each with varying sensitivity and operating temperatures. The resolution of the thermal image is determined by the number of pixels in the detector. While the images produced are not as detailed as visible light photographs, they provide invaluable information about temperature distribution and anomalies.
