But what is Xenon lamp? As a common light source of laser equipment, is usually called laser xenon lamp and pulsed xenon lamp. Xenon lamp is a photocell or flashlight filled with xenon. Xenon is chemically inert, unable to burn or combustion. It is a natural rare gas with the largest molecular weight and the highest density. Xenon high-pressure lamps emit very strong ultraviolet radiation, which can be used in medical treatment, spectrographic production and various industrial laser equipment, such as laser welding machine.
In this case, Φ9X125X270, Φ9 indicates the diameter of xenon lamp, “125” indicates the arc length of a xenon lamp, " 270 " indicates the total length of xenon lamp.
