How Projection Type Works

Throwing light on permeable work piece such as glass and film, and the image projected on a screen is visually inspected.
This method reduces the effort required of operators since it minimizes. 
This allows inspection results to be confirmed by multiple people at once, which contributes to benchmarks unification.
