Environmentally-Resistant ZnS Lens for Far-Infrared Cameras

摘要

Far-Infrared (wavelength: 8 -12pm) Cameras can visualize targets by sensing their surface temperature without using any light source. For this reason, this type of camera is used widely in night surveillance systems, night vision systems installed in vehicle, household electrical appliances, and other equipment and apparatus. Although the market for these cameras expanding steadily at an annual rate of about 10 percent or more, they are very expensive. Cutting the prices of both infrared sensors and Far-Infrared optical lenses is essential to keep popularizing the cameras into the future.
