What is it? 3D-printable adapter, which fits into commercial thermal cameras and adds a 18mm ZnSe CO2 laser lens to the optical path. This greatly improves the imaging quality on small electronics / SMD parts. Before / After Sample photos of PCB with 0603 LEDs: Internal mounting 7 small rod magnets are used to snap the lens into the camera magnetically. The lens to be easily removed for operation at regular focus distances.
