Burn-mark inspection after heat treatment

This is an example of an external post-quenching appearance inspection. Inspections for defects colored similarly to how the product is colored 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 color of the burn marks from that of the finished product.
