Infrared glasses

When using infrared glasses, you can actually see infrared rays from the outside world. Therefore, when using it, we can also use it at night, and when using it, we can use it in the dense forest, which is the most important thing to facilitate the detection of people or animals. This is just something we need to pay attention to.

When using infrared glasses, you must use the photoelectric conversion mode to convert all infrared rays into some electron flow, then use electron multiplication, and finally use the electrons to hit the fluorescent screen to turn it into visible light. We must pay attention to these knowledge points, and we must focus on them because they are the most important.

The purpose of lens coating is to reduce reflections, increase light transmittance and improve observation brightness. Different coating colors have nothing to do with quality. The lighter the coating and the less reflection, the better. However, in recent years, various red-film and yellow-film binoculars with strong reflections and sparkling lights have appeared on the market everywhere, which are very attractive to consumers. Are binoculars with red and bright objective lenses night vision binoculars? The explanation of "infrared, sub-infrared, ruby ​​coating, gold coating, all-weather night vision binoculars" and so on is incorrect. In order to reduce costs, most ordinary telescopes on the market use plastic bodies and tubes. Only a few high-end products and military models use all-metal structures. They are expensive, but their durability is unparalleled.

The military rangefinder telescope is equipped with a rangefinder in the right eyepiece, which can roughly determine the distance between targets through calculation. But for sightseeing, the dense lines are a bit troublesome. Moreover, the rangefinder type telescope has separate focusing for the left and right eyepieces, which is a bit troublesome. So if there is no special need, there is no need to buy a rangefinder type.

When using infrared glasses, it is necessary to choose a more practical one between seven times and twelve times according to personal preference and the purpose of the infrared glasses. If used in reconnaissance or navigation, it would be ideal to buy some high-end telescopes. However, when using them, they still need to be fixed with a tripod.
