Tungsten Disulfide Used in Infrared Thermal Imager

Tungsten disulfide can be used in the lubrication of lens tube to prolong its service life. Lens tube is the main rotating part of infrared thermal imager. It is important to provide stable lubrication for the lens tube as the working environment of infrared thermal imager is complex.

Infrared thermal imager is a kind of equipment which transforms the temperature distribution image of target object into a visual image through infrared radiation detection, signal processing, photoelectric conversion and other means. The equipment has high application value in both civil and military aspects. It is first used in military and then applied for civil use. It is widely used in R & D, industrial detection and equipment maintenance.

The infrared thermal imager is usually composed of optical mechanical component, focusing and zoom component, correction component, imaging circuit component, infrared detector and refrigerator component. The optical mechanical component consists of infrared objective and structural parts. And the infrared objective is used for convergence imaging of the object’s thermal radiation while the structural parts are mainly used to support and protect the relevant components. Among them, lens tube is the main rotating part of the infrared thermal imager.

Infrared thermal imager with precise structure is often used in polar, desert, swamp, mine, disaster search and rescue and other complex environments. Therefore, the lubrication of lens tube, the main rotating part of the infrared thermal imager, is extremely important.

As a new type of solid lubricating material, tungsten disulfide has good lubricating performance, excellent anti-friction property and high temperature and extreme pressure resistance. Even under bad working environment such as high temperature, high pressure, corrosion, vacuum and so on, it can still provide high-quality lubrication.

Therefore, tungsten disulfide has become an irreplaceable choice in the lubrication of lens tube and greatly improves its service life.
