Night vision goggles were invented for use by the military. Over the years, they have become popular among law enforcement agencies and hunters. The technology that makes the night vision possible is called an infrared image intensifier tube. The intensifier tube houses a photo cathode that transfers photons of light energy into electrons by releasing similar electrons from atoms inside the tube itself. This process helps to multiply the electrons and then illuminate the image as the electrons reach the phosphor screen. This process can be duplicated at home by using a simple method and an old webcam.
In this instructable I wil explain how you can transfer your old webcam into a nifty Night vision cam.
Almost any webcam can be used because all of them have pretty much the same parts in this instructable I will be showing you an old Logitec Quickcam with a poor quality of 640X480 px but every old cam will do the trick.
Step 1: Disassemble the thing
Unscrew the body and carfully open the case, in other words tear it apart.
We are foccusing on the lens wich can be screwed of, it is a bit thight but it can be removed.
Once the lens is of whe need to dismatle it completely without damaging the lens so be carefull that you dont scratch the lens.
When the toplens is removed some other parts can be found. the little square thingy is the filter that stops the Infra red light so whe want to remove that part.
