Burn-mark inspection after heat treatment

This is an example of an external postquenching appearance inspection. Inspections for defects coloured similarly to how the product is coloured can be unstable under conventional lighting. Multi Spectrum Mode allows for stable inspections by extracting only the burn marks required for detection, even when it is difficult to distinguish the colour of the burn marks from that of the finished product.
