Low-light gun aiming sight

The sight is mainly used for aiming and shooting various types (different types of lens bases are selected according to needs) under low illumination at night, and can also be used for observing and searching targets. At night, under the condition of no artificial illumination, the scenery (or target) in the natural environment is irradiated by starlight, moonlight and atmospheric glow, and the scenery emits or reflects light into space while being irradiated. When the objective lens of the sighting telescope receives light from the scene (or target), it is imaged on the cathode surface of the image intensifier which coincides with the image plane of the objective lens. When the image intensifier receives this weak optical image, it is converted into an electronic image and then enhanced by tens of thousands of times under the action of the strong electric field of the electronic optical system inside the image intensifier. The enhanced optical image is displayed on the fluorescent screen of the image intensifier and further amplified by the eyepiece, so that human eyes can observe.

Matters needing attention

1. It is forbidden to open the objective lens shield during the day to avoid damaging the core devices.

2, it is strictly prohibited in the use of state to strong light.

3. Turn off the power supply when not in use and take out the battery.

4. When using an external power source (two No.5 batteries), the battery in the host should be taken out.

5, it is forbidden to twist the red valve screw.
