Image: 24 Million Watt high speed flash through welding lens

Description: This photo shows an 85 joule flash discharged in 3.5 microseconds, as seen by the camera through a shade 10 welding filter, (the kind so dark that you can barely see anything through it). While moderately low in energy, the flash produced is extremely intense, from the highly concentrated electrical pulse (equalling 24 million watts), and has no problem penetrating the very dark filter. Due to miscalculation for capacitance, by omitting special circumstances which need to be taken into account at flashes below 10 microseconds[1], the current density is very high which produced the very bluish flash, easily visible, (even lighting up storage bins and a chair across room), through the green arc welding lens. The very high current-density produced an arc temperature of approximately 17,000 Kelvin. This centters the output of the arc at around 170 nm, which is near the UV cut-off for the quartz-glass tubing. References ↑ http://optoelectronics.perkinelmer.com/content/RelatedLinks/CAT_flash.pdf
