Tungsten alloy collimator is a device used to restrict the photon acceptance angle to provide positional information for detected photons. SPECT tungsten alloy collimator is a thick sheet of tungsten alloy of high atomic number, pierced by an array of holes.

Ion fan tungsten needle refers to the tungsten needle used for an ion fan. Wherein, the ion fan has excellent anti-static performance, can prevent static electricity pollution, and is small, light, and easy to install. It is an ideal equipment for personal static protection areas such as electronic production lines and maintenance stations.

Tungsten alloy collimator is an important part of a gamma camera (γ camera). And it plays the role of radiation guidance (collimation) and radiation protection (reducing the patient's exposure to gamma rays) on the core component of the gamma camera.

Argon arc welding tungsten needle is more often known as argon arc welding tungsten electrode. And such a needle may be a thoriated tungsten electrode, a cerium tungsten electrode, or a lanthanated tungsten electrode, etc.
