flashtube การใช้

• The lighthouse has an iron xenon flashtube beacon.
• Modern open path systems typically use a xenon flashtube powered by a capacitor discharge.
• The flash from a single ablative flashtube can also be more intense than multiple lamps.
• Carbon nanotubes are particularly susceptible to this spontaneous ignition when exposed to the light from a flashtube.
• The closer a flashtube operates to its explosion energy, the greater the risk becomes for catastrophic failure.
• The most common gas used in an ablative flashtube is air, although sometimes cheap argon is also used.
• The flashtube was invented by Harold Edgerton in the 1930s as a means to take sharp photographs of moving objects.
• The synthetic ruby rod is optically pumped using a xenon flashtube before it is used as an active laser medium.
• In the center of a white flash ( leakage from the xenon flashtube ), a red spot was briefly visible.
• For any given amount of light energy created, the diode lasers give off about as much heat as a flashtube.
• When operated below 30 % of the explosion energy, flashtube lifetime is generally between a few million to tens of millions of flashes.
• The flash that emanates from a xenon flashtube may be so intense that it can ignite flammable materials within a short distance of the tube.
• It consists of either a rotating disk with slots or holes or a lamp such as a flashtube which produces brief repetitive flashes of light.
• Because the cathode is more emissive than the anode, the flashtube is polarized, and connecting the lamp to the power source incorrectly will quickly ruin it.
• A flashtube will usually shut down before the capacitor has fully drained, and it may regain part of its charge through a process called " dielectric absorption ".
• The high-voltage leads of the trigger-transformer are connected to the flashtube in series, ( one lead to an electrode and the other to the capacitor ).
• The light source is commonly a xenon flash lamp, or " flashtube ", which has a complex spectrum and a color temperature of approximately 5, 600 kelvins.
• On the other hand, melt expulsion, the means by which a hole is created through melting the material, dominates when a flashtube pumped Nd : YAG laser is used.
• The smoke was illuminated from behind with a flashtube in front of light-blue foil, and the lightbulb with a strip light ( " softbox " ) obliquely from behind.
• As the duration of the flash that is emitted by a xenon flashtube can be accurately controlled, and due to the high intensity of the light, xenon flashtubes are commonly used as anticollision beacons, and other similar applications.
