WGS45-4
產品適用范圍
微光夜視儀廣泛應用于軍事、刑偵、輯毒、輯私、夜晚監控、保衛等領域。
主要功能
WGS45-4微光夜視儀具有物鏡調焦、視度調節、輔助照明等功能。
主要性能指標
物鏡組V
物鏡可沿光軸前后移動，使不同距離處的景物都能成像在像增強器的陰極面上，俗稱調焦，調焦范圍250 mm～∞。
中部組
物鏡組、目鏡組、連接機構通過中部組連接成一體，微光夜視儀的核心元件——NVT-7像增強器裝在中部組內。
目鏡組
目鏡組把像增強器熒光屏上的圖像放大后供人眼觀察，其視度可調節，調節范圍為-6SD～+2SD。
物鏡組
物鏡蓋的端面中央有一個小孔，在白天檢查微光夜視儀時，可減小進入物鏡內的光線強度，起到保護像增強器的作用。不使用微光夜視儀時，應罩上物鏡蓋。
眼罩
眼罩是可起控制眼點位置的作用，同時還可防止使用中對操作者眼部的沖擊振動及防止目鏡光線外泄而暴露目標。
開關
開關有3個擋位，設置在中部組上，初始位置為關閉狀態，順時針轉動開關到中間擋位，夜視眼鏡開始工作，繼續順時針旋鈕開關到下一個擋位，可打開輔助照明功能。
輔助光源
為了滿足在極低照度（<10-5lx）下工作的需求，本產品配有紅外輔助光源。當照度低于<10-5lx以下時，繼續將電源開關順時針旋轉一個檔位，即可開啟輔助光源，提高成像質量。

WGS45-4
WGS45-4night vision device is widely used in military, criminal investigation, Drug Enforcement, smuggling, night monitoring, land defense and other fields.
The Main Function
WGS45-4 night vision device has the functions of eyepiece focusing, visibility adjustment, auxiliary lighting and so on.
Main Performance Indicators
The objective lens group
Variable Focus
Focusing range ： 250mm
The central group
Objective group, eyepiece group and connecting mechanism are connected into a whole through the middle group, and the NVT-7 image intensifier, the core element of night vision instrument, is installed in the middle group.
The eyepiece group
The image on the phosphor screen of the eyepiece
is enlarged by image intensifier for human eyes to observe, and its visibility can be adjusted from -6SD to 2SD.
The objective lens group
There is a small hole in the center of the objective lens cover, which can reduce the intensity of light entering the objective lens and protect the image intensifier during daytime inspection. Objective lens cover should be closed when night vision device is not in use.
The eye mask
The eye mask can control the position of the eye, at the same time, it can also prevent the impact on the operator's eyes during use and prevent the exposure of the target due to the leakage of eyepiece light.
The switch
The switch has three gears, the initial position is closed,turn the switch in a clockwise way to the middle gear, night vision device start to work, continue to turn the clockwise knob to the next gear, can open the auxiliary lighting function.
Auxiliary lighting source
In order to meet the requirements of working under very low level illumination (<10-5 lx), the product is equipped with infrared auxiliary light source.
When the illumination is lower than <10-5 lx, continue to turn power switch in a clockwise way by one gear to open the auxiliary light source and can improve the imaging quality.
