Focus
Some focus mechanisms that can help your imager give a clear picture are- fixed, manual, autofocus, multifocal, and laser-assisted autofocus.
Temperature range
Cameras with a wide temperature and can select range automatically based on the scene are a good option for acquisition.
Color palettes

How to use a Thermal Imager
From the above discussion, we got to know a lot about thermal imaging products and their features. Now the question is, how to use a thermal imager? Most of us predict its use like costing an arm and leg. But there is no such thing. All you need to know is the proper steps of using a thermal imager.
- First and foremost, you have to define the task you are going to do. Suppose you are going to inspect a building. In prior, you have to see if there is any noticeable draft or cold inside or not.
- Then start your inspection from outside and take thermal images from there. Conditions are okay. Consequently, you can be able to compare the results with images that have flaws.
- In the next step, you have to look at the condition from the inside by thorough preparation. Just prepare your interior thermal scan and ensure accuracy.
- Now comes the airtightness test. This test makes smaller to more minor cracks visible. But, you will need to apply this technique only if you are using your thermal imager for building purposes.
How do thermal imagers work?
Thermal cameras are also known as thermographic cameras. They are a valuable alternative to detect radiation of the electromagnetic spectrum in a long-wave infrared range.
Their wavelength generally ranges from 8 to 14 micrometers. In addition, there is a visible spectrum in thermal imagers. This spectrum contrasts with digital cameras and regular film detecting light in a portion of the electromagnetic spectrum. Again, the electromagnetic spectrum ranges from 0.40 to 0.75 micrometers.
Thermal cameras don’t find it a hindrance to visualize when there is no visible light. Because the objects’ temperatures are above 0 kelvin, e.g., -273 degrees Celcius, which emits infrared radiation, conversely, some thermal cameras can only see those objects which are above -50° C.
Frequently Asked Questions
What can a thermal imager detect?
Thermal imagers are a great alternative to detect medical conditions, such as strain injury, arthritis, muscular pain, circulatory problems, and so on. Many physicians use thermal imagers to detect such health problems.
Can thermal cameras be dangerous?
No, thermal cameras are not dangerous. They are noninvasive, non-contact, and gains a passive imaging system. As a result, they can easily measure heat emissions by the human body.
Why are thermal cameras different from infrared cameras?
Usually, infrared cameras use short wavelengths to illuminate by an active IR system. At the same time, thermal imagers use mid and long wavelengths. They are passive and sense variances between heat.
What are some best thermal imagers?
Some best thermal imagers in the market are-
- Android and iOS: FLIR One Gen 3
