Detecting thread on the nut

Using the NF‑DA06 spot‑size adjustable lens together with the NF‑DM02‑G4 coaxial diffuse‑reflective fiber‑optic cable, the presence or absence of tapping in a nut can be detected. When no tapping is present, the light does not reflect back to the lens, whereas a tapped nut produces a reflected signal, allowing reliable differentiation.
