 Scientists in the meteoritics and planetary science field as well as private collectors of meteorites use loupes as one of their primary tools in meteorite classification and study, and also for simple examination in the field during meteorite recovery.Due to the extremely small size of many modern surface-mount components used in compact electronics, engineers often use a loupe to inspect the completed circuit board for manufacturing defects such as solder bridging and missing or misaligned components.While soldering or reworking surface-mount components by hand a loupe can be used for identifying and aligning parts.
