Transparent and semi-transparent materials are among the most demanding subjects for machine vision: cracks, inclusions, bubbles and coating defects produce weak contrast under standard lighting and typically require backlight, dark field or wavelength-specific techniques.
Application notes in this sector
- Plastic injection molding: part completeness with darkfield lights
- Vision lighting for glass and transparent material inspection
Each application note describes the inspection problem, the recommended illumination technique, the applicable RODER products and the related technology pages. The pages of this sector are being published progressively.
