Cesium tungsten bronze is widely used in near-infrared shielding materials due to its excellent absorption performance of infrared and ultraviolet rays, and is used as heat insulation additives for automotive glass, architectural glass, and agricultural greenhouse films.

A collimator is a device used to transform the divergent light or other radiation from a point light source into a parallel beam, and also is an absorber device used to limit X-rays, gamma rays, or nuclear particle beams to the size and angular spread required for a specific application. Normally, special measurements in spectroscopy and geometric and physical optics require this kind of light collimation.

Tungsten, also known as Wolfram, is a rare metal known for its highest melting point of all elements. In addition to excellent temperature resistance, the material also has strong abrasion resistance and chemical resistance. These good properties make it an ideal material for components that operate at extreme temperatures.

Many analytical and medical devices are using thorium tungsten wires as ion source. Why use thorium tungsten materials? What about tungsten or neodymium tungsten materials?
