One of the coolest things in optics that most people don’t know about is the Night Vision technology. You might have seen a clip of two in the movies where the smart guy is seeing things in the night, but apart from that, it’s hardly the case that people search about the working mechanism of such tools.
Night vision devices are sophisticated devices that allow us to see things clearly in the nighttime. These devices are used both by military personnel and hobbyists who love to discover the jungle at night.
There are tons of useful add-ons like the thermal clip on that make night vision devices ideal to use for current needs. Are you interested to know more about these amazing devices? Keep reading this article to find out more!

Latest Night Vision devices
The first thing you have to know about the night vision cameras is that they are not much different from the standard cameras. It’s the presence of a magnification mechanism that differentiates a normal camera from a night vision device.
These night-vision cameras are built to capture the faintest light rays. Once the light ray makes its way to the night vision camera, the system’s presence inside starts the magnification process and allows us to see things clearly that are impossible to be seen with the naked eye.
A night vision camera is no different from a regular one if the magnification mechanism is removed.
The reason why night vision cameras are popular in the market is the fact that they get regular updates from companies around the world. Gen 4 is the latest generation of night vision cameras available in the market. However, there’s still more to be done to refine these cameras. A major problem with night vision cameras is that they are not useful during the twilight time.

Infrared Cameras
Infrared cameras provide mid-range performance compared to Night vision cameras and Thermal imaging devices, and these devices are simply known as I2 devices. The good thing about Infrared cameras is that they don’t have to depend on any light source to get the job done.
It doesn’t take long for the camera to throw infrared rays on an object and receive it back to picture the target. However, this feature itself comes with a huge disadvantage, and it’s impossible to send the infrared light over long distances, and infrared cameras fail to work for long-range operations.

Thermal Imaging Devices
What’s the easiest way to sense something from a long-distance? If visible light is not present and it’s impossible to send infrared rays over a long range, thermal imaging devices are the only good option.
These devices can capture the thermal heat released by organisms or other mechanical objects. The good thing about thermal cameras is that they don’t have to produce any heat or infrared rays to capture objects.
Thermal cameras traditionally produce black and white images. However, they can also produce colored images too.
