Infrared Lens
Daheng Optics provides optical design and manufacturing for infrared lenses. Their main application is thermal imaging: an infrared detector and imaging objective receive the distribution of infrared radiation from a target and project it onto the detector's photosensitive elements to obtain a thermal image corresponding to the object's surface temperature distribution. In simple terms, an infrared imager converts invisible infrared energy into a visible thermal image, whose colors represent different object temperatures. Main applications include security surveillance, vehicle and marine navigation assistance, medical thermal imaging, and gun-sight systems. Security surveillance has substantial demand and is a major infrared-product market, including urban security, petroleum storage, power monitoring, and forest-fire prevention. Vehicle assistance systems avoid glare and improve safety and represent a future development trend. Marine navigation generally uses large, long-focal-length lenses to improve recognition of scenes during ocean voyages. Medical temperature-measurement lenses commonly have short focal lengths of 8-25mm and observe overall or local temperatures at distances of 2-3 meters to assess changes in clinical cases. Gun-sight lenses are commonly manually focused; specialized military systems may use dual-field-of-view lenses.
