How To Make Night Vision Camera At Home

Build your own night vision from an ordinary camera

Night vision is rather interesting device that has always fascinated all handymen. With the emergent era of digital cameras at present you tin build yourself such a device from commercially bachelor materials. CCD or CMOS photographic camera sensor itself is sensitive to infrared radiation up to about k nm. Its sensitivity to IR radiations is artificially limited using infrared blocking filter to the range of wavelengths the human heart tin can come across. As nosotros need a sensor sensitive to infrared radiation, we want to remove the filter. You can encounter its removal footstep by step on photos below. And then we will add together an infrared illumination to the camera to turn information technology into a night vision camera. As infrared low-cal source I used infrared laser diode 808nm 1W, working with reduced output of 500mW. I equipped the diode with a matte filter which spreads the light. The advantage of the laser diode is very loftier efficiency. The disadvantage is that it is hazardous. Safer illumination can use made with infrared spotlight on the principle of incandescent bulb (reflector with filter which passes only infrared radiations) or infrared LED. Suitable are LEDs with a wavelength of near 840 or 850 nm. There are too LEDs with a wavelength 940 or 950 nm on the market, but the CCD is less sensitive to these wavelengths. And so this is the way yous can build an agile dark vision - nighttime vision with invisible infra-red illumination. This night vision does not only permit you lot to see in the dark, just as well to take pictures or shoot videos in dark.

Alert!!!
- Grade Four Laser! Invisible light amplification by stimulated emission of radiation radiations - at that place is a serious eye injury hazard. Everything you do at your own risk. I do not take responsibility for any damage that you crusade yourself or anyone else. For safer operation, utilize a unlike source of IR illumination than the IR light amplification by stimulated emission of radiation.
- Photographic camera flash contains circuits with lethal voltages! capacitor in the photo flash may remain charged to dangerous voltages even later the power supply (battery or adapter) was disconnected.
- The modification of the camera may exist irreversible and the camera may thereafter be unsuitable for normal use. This modification can completely destroy the camera.

Camera I chose to rebuild to a night vision photographic camera.

Disassembling and testing the camera earlier removing the infrared filter.

After removing the filter, the camera sensitivity to infrared radiation increases many times. The picture is infrared remote control LED (probably 940nm).
