The rise of the Seta light is closely linked to the "New Mediterranean" and "Japandi" design movements. These styles emphasize a connection to nature, the use of raw materials, and a palette of neutral tones.
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. seta light
The contrast ( C ) generated by Seta Light can be approximated as: The rise of the Seta light is closely
