The application of barium tungsten electrodes in the field of photography is mainly reflected in the following aspects:
Xenon flash lamp
Barium tungsten electrodes are often used to manufacture electrodes for xenon flash lamps. Xenon flash is a commonly used fill light device, especially in low light environments, which can provide strong and fast light, helping photographers capture clear and bright photos or videos. Due to the low escape work and high electron emission ability of barium tungsten electrodes, xenon flash lamps can quickly achieve the required brightness and maintain stable luminescence performance.
Laser rangefinder
In laser rangefinders, barium tungsten electrodes are also used as electron emission sources. The laser rangefinder determines the distance of the target object by emitting laser and measuring the time it takes for the laser to reflect back. The excellent performance of barium tungsten electrodes can ensure that the laser rangefinder emits stable and accurate laser pulses, improving ranging accuracy and reliability.
High speed camera
In high-speed cameras, barium tungsten electrodes are also used to manufacture light sources. High speed cameras need to be able to capture rapidly moving objects or phenomena, thus requiring light sources with high brightness and fast response. Barium tungsten electrodes can provide stable and high brightness light, allowing high-speed cameras to capture clearer and more accurate images.
