Frequently asked questions

Q1: How to make a thermal imager?

To do it you only need a digital camera (inexpensive), a screwdriver and glue. First, two pieces of square-shaped film negatives must be cut. These should end in black ends. Take the digital camera and open it with a screwdriver. Remove the charging device, which will be located at the back of the lens. Inside it is the infrared filter, which is a small piece of glass. Add glue to the film negative and then place it in the loading device, wait for it to dry and reassemble the camera. Finally, take a photo in the dark and you will notice different colors.

Q2: How to calibrate a thermal imager?

The calibration of a thermal imaging camera will depend on the model, since each instrument has an operating mechanism. Therefore, before rushing to make adjustments, it is recommended to take some time to read the instruction manual that the manufacturer has provided with the device. A correct calibration will guarantee a good operation, traceability of the measurements and reliability.

As it is not a simple process, there are some companies that carry out the process in calibration laboratories, in which they check that the measurement captured in the infrared images is within the tolerance ± 2 ° C or ± 2%, according to the manufacturer’s standards. . To achieve this, several blackbody sources must be used at different temperatures. In turn, the black body reference sources are periodically calibrated by international entities and take into account the parameters of an environment controlled by a central computer.

Q3: How to read temperatures on a thermal imager?

The reading will depend on the model and brand of the thermal imager used for the measurement. In most cases it is necessary to make use of a special application or software, a resource that will allow the data collected in the images to be reported.

Q4: Who invented the thermal imaging camera?

The thermal imaging camera does not have a single inventor because it is the product of several advances that have been presented over the years. So your invention cannot be attributed to just one person. It was Herschel who discovered infrared radiation during the 19th century and by 1920 it was possible to measure the radiation. Some time later, radiation was measured in relation to temperature.

Then, in World War II, infrared radiation was used for military purposes for missiles. At the end of the war, a Swedish company known as AGA brought the first commercially used thermal imaging camera to market in 1960. By the 1980s, more manageable models appeared and, between the 1990s and 2000s, competition between brands provided a greater range of applications.

Q5: How accurate is a thermal imager?

Thermal imaging cameras are instruments that stand out for having an adequate level of precision. However, reliability will depend on the model and brand, since each of the alternatives has different technological developments. Most of the models have in their specifications the variation in precision that can be, in the best of cases, between ± 2% of the measured value.
