Seta Light Official

A manufacturer of precision lenses required non-destructive inspection for subsurface scratches (depth < 1 µm) after polishing. Standard brightfield microscopy failed because scratches did not scatter light strongly. Using Seta Light (single fiber-optic guide, 20° incidence, 10 mm from sample), scratches appeared as bright linear features against a dark background. The method reduced false rejects by 34% compared to visual inspection under ring light.
