Creating Contrast for Plastic Surface Inspection with a UV Light and Bandpass Filter

Using a UV light source without a filter over the lens creates insufficient contrast for inspection. When a UV light source is used together with a MIDOPT® BP324 UV Bandpass Filter on the lens, the contrast dramatically improved allowing for clear inspection of the surface defects on the plastic.

UV Fluorescence Paint Marker Inspection

When a railroad tie with a metal endplate runs through vision inspection, a UV (325nm) light is used with a BP525 Light Green Bandpass Filter to ignore (block) the reflection from the end-plate and pass only the emission of the fluorescent paint marker in order to determine orientation of the tie.
