Helmet Mounted Night Vision Goggles

HAWKEEP HELMET MOUNTED NIGHT VISION GOGGLES 

 

This night vision goggle system has repeatedly proven its worth in combat, and is the highest-quality night vision system on the market. The night vision can be outfitted with high-performance Gen 2 and Gen 3 image intensifier tubes.

 

They are waterproof, rugged, and reliable by being made of top quality grade materials. The goggles provide a high quality night vision experience at any time, in pitch black conditions, in wet or dirty conditions, and in situations when your hands are busy. The night vision have a built-in infrared illuminator which creates "invisible" light, allowing your goggles to see in completely lightless situations. The night vision is equipped with Automatic Brightness Control to adjust image brightness in changing light conditions to maintain image definition and clarity. Additionally, the night vision has a bright light cut-off feature to protect the image tube from sources of intense light, and a flip-up shut-off feature that can be used with the optional helmet mount system. The night vision goggles have proven themselves as a high performance NV device in detection, rescue and surveillance missions in extreme low-light conditions. This versatile system can be used as a handheld or hands-free goggles, or with an optional long-range Lens or compatible objective lenses that allow converting the night vision goggles into a powerful NV viewer with 3.0x, or 5.0x, magnification, depending on the lens the device is paired with.

 

Additional features include IR on and low battery indicators, automatic brightness control and auto-shut off function that shuts down the device within seconds when accidentally exposed to bright light, and an integrated IR illuminator for use in extremely low light conditions.These goggles ship with included accessories to make these goggles ready to operate right out of the box, a case, batteries, a head mount assembly, and many more!

Distortion refers to the degree of distortion of the image of an object formed by an optical system relative to the object itself. Optical distortion refers to the degree of deformation calculated in optical theory.

 

Optical distortion is an important optical indicator of aviation transparent parts. It refers to the optical defect that causes the image of the observed object to be distorted when observing the object through aviation plexiglass.

 

Barrel distortion, also known as barrel distortion, refers to the distortion phenomenon of the image caused by the optical system in the form of a barrel-shaped expansion. Barrel distortion is more common in photographic lens imaging, especially wide-angle lens imaging. The image of a funhouse mirror that makes people short and fat is a more vivid example of barrel distortion.

 

Pincushion distortion, also known as pincushion distortion, refers to the phenomenon that the image caused by the optical system "contracts" to the middle. Pincushion distortion is more common in telephoto lens imaging. The image of a funhouse mirror that makes people thin and tall belongs to pincushion distortion.
