This is a macro lens which fits the GuideIR PC210 thermal imaging camera. The adapter makes it possible to focus on electronics close by.
The adapter snaps easily around the thermal camera. It can be removed easily as well, when you want to use the camera without the macro lens. The adapter is 3d-printed in sturdy PETG plastic.
The macro lens also fits the GuideIR T120 but due to the lower resolution we recommend usage with the PC210
