When choosing an infrared thermal imaging camera, you may be wondering if you need to select an additional lens that is suitable. So the first thing you need to know is exactly what you're buying a thermal imaging camera for.
In general, the standard lens provided by infrared cameras can meet most requirements. However, for some special purposes, additional infrared lenses are required. The table below describes detailed differences between them.
For the telephoto lens, it’s suitable for targets from a long distance.
To see more detail of objects at close distance, wide angles are better.
Macro lens is for seeing very tinny target such as chip circuit.
