Flame penetration imaging can be used to take movies through flames, arcs and explosions. When an arc or laser welding process is imaged with a normal imaging system, the high brightness of the plasma saturates the camera and no detail can be seen. VisiWeld systems eliminate the glare to give a clear image of the weld process.

Sparkler without visibrite: Conventional high speed movie of firework. Flame is over-exposed (white) and unburned region is under-exposed (black)

Sparkler with VisiBrite: VisiBrite movie of same firework. Note that the flame has disappeared, and we can clearly see the melting process.
