Pixel pitch, explained | 12 µm vs. 17 µm | Choosing the right sensor

If you are looking at some of the new devices by Pulsar, you must have noticed that they have different sensors. Typically, when looking at a sensor’s parameters, we first look at the resolution. And we all know that the bigger the resolution, the better the image quality.

But you may have noticed that there’s something else written next to the resolution: in our case, it’s either @12 µm or @17 µm. And that is pixel pitch, or, in simpler terms, pixel size. And while the resolution has a lot to do with image quality, the pixel pitch is responsible for the sensitivity of the sensor. And this is particularly important in tough weather conditions – rain, fog, cold mornings, and so on.

So, we hope this helps next time you’re choosing a thermal imager – at least now you know that’s it not only the size of the sensor – but that of the pixel itself, too – matters!
