Generation 1 Night Vision Camera
Generation 1 Night Vision Camera

Night vision is something that fascinates me as well as thermal, and the modern mix of both in some highly advanced military-spec devices. I had always wanted to own one, but never had the money to afford one.
Just before I left for university I read about how some old cameras are very sensitive to infrared light and they have filters stopping them from doing so. Some of these cameras can be dismantled, allowing the filter lens to be carefully removed. I performed this procedure on an old camera, and then to improve it further and mainly out of curiosity, I bought a cheap new 720nm filter which I glued on the front of the camera's outside lens as it matched the diameter roughly. This made it only see in the the infrared spectrum.
The IR filter that I removed:
The photodiode array:
The fascinatingly beautiful mechanism of the camera's zoom feature:
The new infrared filter lens glued onto the camera produced a purplish image which is quite facinating.
The camera had an ability to see through quite a few objects. This remote in particular produced the most impressive image result as it makes the camera function extremely like an x-ray machine.
I assume this is because the engineers who designed this remote had exactly this in mind when thinking about how the remote could transmit a signal discretely through its casing. The remote's light is also visible around this wavelength as is demonstrated next.
The light can be seen flickering at different frequencies when pressing different buttons on the remote.
And finally, Sandy in infrared.
Maybe not as impressive as the remote.
