Common night vision mirror... May divide into two big systems is the enlargement photosource star light night vision mirror, with picks up the infrared spectrum the infrared night vision mirror Star light night vision mirror: By optics lens, the weak light which will reflect by the object, or the naked eye blind infrared, the focusing will form image in the electric eye front table side, the energy conversion after the electron, will enlarge several thousand times in the electric eye to tens of thousands of times, again by the electric eye end fluorescent screen, will transform the naked eye obviously bright image. The star light night vision mirror and the common telescope are different, the attenion is can see under the extremely low brightness the goal, as well as broad field of vision, therefore selects the lens the specification mostly to belong to the short focal distance, the big aperture, the percentage usually all below 6 times, is suitable the head which drives to at night wears the type type, in order to judge the distance, mostly has not enlarged the percentage (1X). The star light night vision mirror is unable to demonstrate the colored image, in order to coordinate the human naked eye the photosensitive ability, on the fluorescent screen image all is the green single color Infrared night vision mirror: All organisms can send out the heat energy (in particular warm-blooded animal), but can give off heat the object surely can send out the infrared, but these infrareds, actually all are the person naked eye are unable the sensation; The infrared night vision mirror is unable the sensation infrared these person of eyes, the affiliation by optics and the electronic technology, demonstrates on the firefly curtain.... The star light night vision mirror is different which with the star light night vision mirror is the weak photosource enlargement, but completely is not having the photosource under the condition (for example in darkroom, after perhaps in seal room) the star light night vision mirror nearly does not have the use (because 0 enlargements dozens of times or 0), but the infrared night vision mirror certainly does not need the photosource, because the heating element was a best photosource therefore infrared night vision mirror suitable Yu Shihnei environment.... But the infrared night vision mirror, mainly is comes out the infrared to the developing, therefore, certainly cannot have the clear image under the infrared night vision mirror (to compare to star light night vision mirror) Although is divides into these two big kinds... But newest night vision mirror. Actually also has the union star light night vision mirror and the infrared night vision mirror design so first, each other truncation is long is not short, lets the night vision the function even more great strength...
