How to choose a thermal imaging zoom lens or a thermal imaging fixed focus lens

  The thermal imaging effect focuses on the movement, and the choice of fixed focus and zoom thermal imaging depends on the specific project requirements. The difference between fixed focus and zoom thermal imaging: 1. The price difference is huge. For example, the price difference between 100mm fixed focus and 20-100mm zoom thermal imaging is nearly doubled. The price difference is so big, mainly because the zoom thermal imaging process is complicated, and multiple controllable lens groups need to be built in the zoom lens. 2. Performance difference. At a focal length of 100mm, the imaging effects of the two are the same. However, when looking at a close target within a range of 10 meters, due to the long focal length of the fixed-focus lens, the image of the close target is too large, but the whole thing cannot be seen. For example, when you see a person, you can only see part of the body. The zoom can be changed to 20mm focal length, and multiple targets can be seen within 10 me...
