The working principle of infrared thermal imaging equipment is quite direct and concise. Its working process includes the following key steps:

Perception of infrared radiation - infrared lens

One of the main functions of infrared thermal imaging lens is to capture these emitted infrared radiation. This is done by special equipment inside the lens, which is very sensitive to infrared radiation.

Conversion of radiation into electrical signals - infrared detector

The captured infrared radiation is then converted into electrical signals. This step is completed by infrared detectors, which convert the intensity of infrared radiation into electrical signals.

Conversion of electrical signals into images - signal processing circuits

Finally, these electrical signals are processed into images that we can understand. This is done by signal processing circuits, and this conversion is very fast and accurate, so we can see the thermal image of the object in real time.

Observation of infrared heat distribution

Infrared thermal imaging equipment can help us see the heat distribution inside an object. This is because infrared thermal imaging cameras can receive and convert infrared radiation emitted by an object, and the intensity of infrared radiation of an object is directly related to its temperature. By observing the heat distribution inside an object, we can understand the internal structure of the object.

Industry Applications

· Medical field: Doctors can use infrared thermal imaging equipment to view the heat distribution inside the human body, so as to find possible lesions and help diagnose various diseases.

· Building detection: In the field of construction, infrared thermal imaging equipment can be used to check the insulation inside the building and help find possible heat leakage points.

· Security monitoring: Infrared thermal imagers can work in a completely dark environment, identify camouflage for night vision observation, and detect intrusion risks.

This article mainly explains the infrared lens of infrared thermal imagers, which can be divided into the following types according to their functional applications:

· Fixed focus lens: This lens is the simplest lens. It can only be used within a certain depth of field. Outside the depth of field, the image will be blurred.

· Manual focus lens: By adjusting the hand wheel to change the lens position, the system has a deeper longitudinal observation range, and the image blur caused by temperature can be adjusted.

· Electric focus lens: The lens is driven by a motor, so that the system has a deeper longitudinal observation range, and the image blur caused by temperature can be adjusted.

· Continuous zoom lens: There are many fields of view that can be switched. Users can switch fields of view at any time according to the situation and find the appropriate field of view for observation. The design and installation are very difficult and the cost is very high.
