However, with the appearance of the night vision binocular, a new fervor of purchasing has been blown up. Don’t you think it’s cool and practical?
Night vision binocular is also called as UV night vision instrument. At night, the visible lights are filmy, while the invisible ultraviolet rays are abundant, which could help in observing, searching and driving for humans with UV instrument. Though people discovered the ultraviolet long ago, the UV remote sensing technique was developing slowly due to the restriction of IR components. It is not until 1940 after the innovation of lead sulfide and several UV transmission materials that the UV remote sensing instrument was born.
The night vision binocular was first utilized in military activities by the using of photoelectric conversion technology. So far, the night vision binocular can be classified as active mode night vision binocular and passive mode night vision binocular, for the former one illuminates the target by UV searchlight, while the latter one forms a ‘thermal image’ of the target according to the UV radiation of the target itself, which is also called as ‘thermal image instrument.
Something interesting:
It is reported that the night vision binocular can help in seeing through human’s body with an attachment lens, and these attachment lens are produced by YAMADA DENSHI, the company who is producing light-transmission cameras for military and defense.
