If you are using thermal image cameras in Australia, your goal should be to get a high-quality image. The high quality of thermal images is more than aesthetics. It is important to pinpoint specific areas. We will look at certain areas to help you get high-quality thermal images.
Focus
Focus affects the quality of your image and the accuracy of the temperature measurement data that gets captured by your thermal imagining camera. Blurry images can be worse than not getting an image at all. If your image is not in focus or simply out of focus, your measurement can be off by about 20 degrees. You need to be sure to choose the focus type – manual, fixed, or automatic that matches the distance to the target for your inspection. This way, you will get a clear image that is in focus.
Optics
The efficiency of transmission of infrared energy to the defector is determined by the material used to make the thermal imaging lenses. Thus, directly impacts the quality of the image you get. Losing too much energy through the optics will lead to a loss of detail in your image. The most efficient available material is germanium. It is efficient for transmitting energy to the detector. It is also used with special coatings in high-quality infrared camera lenses. So when buying a thermal image camera, you should consider the optics.
Detector resolution
The number of pixels or detector resolution on your camera is an important factor in the quality of the images you get. Each pixel is designed to detect the apparent temperature of its target area. The more detector pixels on the target, the more detail you get and the more accurate your measurement will be. This means that a high-quality thermal imaging camera has a high-quality detector resolution. However, it is important to understand that the more the detector resolution, the higher the price of your camera.
Field of view
The field of view works hand in hand with the detector resolution of your camera in determining the quality of an image. Field of view defines the area the imager sees at any time. Field of view requirements for your thermal imaging camera varies depending on the application. E.g., a wider field of view is better for inspecting buildings or having an up-close look at an electrical board. Smaller objects benefit from a camera that has a narrow field of view.
Spatial resolution
Both the field of view and detector resolution plays an important role in infrared image detail and this means that you will be happy to know the spatial resolution which is usually measured in mRads. Spatial resolution can be referred to as a method of defining the smallest object that can be detected. When the value is low, the detail of the image is high and this means that the quality of the image is also high. Make sure you consider the spatial resolution of your thermal image cameras in Australia when buying or renting.
