Einführung der Visierlinse

  • Produktbeschreibung:

Als augennahe Komponente des visuellen optischen Instruments, Das Visierobjektiv wird in Verbindung mit dem optischen Frontend-System verwendet. Seine Austrittspupille liegt außerhalb der Linse (Die Pupille des menschlichen Auges fungiert als Blende), and the light rays of the same field of view passing through the exit pupil are parallel rods. Suitable for human eye observation, it is a typical large aberration system, usually the focal length is between 15-35mm, and the exit pupil distance is 10-70mm, and the diopter can be adjusted.

  • Gun sight lens features:

Long exit pupil distance: civilian products are mostly 10-20mm, military products are generally more than 30mm, and the exit pupil distance of gun sight systems is greater than 50mm.

Geringe Verzerrung: Since the eyepiece is directly used for human eye observation, usually in order to preserve the geometric characteristics of the observed object without distortion, TV distortion is generally controlled below 3.5%.

Adjustable diopter: Considering the difference in the strength of different users with far and shortsightedness, and the ability to converge light differently, it is required that the back focus can be adjusted to achieve naked eye observation of different groups of people. Generally, the range of diopter adjustment is required to be from ±3D to ±5D. Wait.

 

 

  • Features of CH8041A:

The existing gun sights on the market are C/CS lens telephoto lenses, which are large in size and inconvenient to carry.

Now there are only 35mm and 50m focal lengths for S-mount lenses on the market.

For the above Chuang’an Optoelectronics specially developed the gun sight telephoto lens CH8041A: 70mm, 1/1.8CA3712A-3, 12MP, for day and night, the weight is only 49g.
