DIY night vision!

This really works and the results are amazing!

 

The background:

 

I've been in to digiscoping for a few years now and have had Nikon coolpix 950 - 4500 camera's, I basically hang the camera off the eye piece of a 40x spotting scope, multiplied by the 4x optical zoom the camera has I can use 160x optical zoom which can give amazing results!

In the middle of the week I stumbled across various sights giving instructions on turning digital camera's in to Night Vision! basically the CCD chip in all digital camera's are sensitive to IR (infra-red light) and to stop IR effecting your images they all seem to have an IR filter on top of the CCD, simply by removing this filter and using an IR light source you can take pictures / movies or just see in the dark!

Now you can see how instantly I came to the conclusion that I could digiscope in infra-red with a rifle scope?

 

So I asked around for an old digital camera I could digiscope with that would be cheap enough to pull apart and risk destroying! a mate came up with a Canon powershot A400 for £10! I set to work and spent a couple of hours with very tiny screws and pcb's all over the place but eventually found the small light blue coloured glass filter between the lenses and the CCD once removed the camera went back together easier than it came apart! (it would have been easier to do a camera someone had already done online!)

 

The results are great! this means I can mount the digital camera on my scope and dismount it without making any adjustments so no dedicated night time rifle! I can take pictures or movies through the scope, the camera still works as a normal daytime camera with a little difference to the colours!

 

 

 

 

The project isn't finished I'd like to find an earlier Nikon Coolpix 900 - 950 as the earlier Sony CCD's these use apparently are more sensitive to IR also these camera's have the ability to adjust the angle of the screen which could be useful, I need to make a hood for the LCD screen as the light from this lights my face up a treat! I need to make a decent IR light source as I'm only using the light source on the side of my Yukon NV at the moment which has a very narrow beam and too short a range for anything useful!

 

 

 

 

The disclaimer: Obviously you are at risk of braking a perfectly good camera if you follow what I have done, you maybe at risk from electric shock if you take your camera apart, you'll almost certainly void any warranty! So DO NOT attempt this unless you are prepared to take FULL responsibility!

OK, been reading 'Home made IR illuminator, Very effective' by PIN, very in depth, it appears the lamp is going to cost me more than the NV lol! but I will be sourcing lighting gels 'congo blue' and 'primary red' as suggested and a high power hand held lamp......

I've got a fair sized roll of both somewhere, if you want a small amount for testing drop me a pm with your address and the size you want.

 

What I found was in single layers there is still a fair amount of visible light coming through, double up and it gets less and less with only moderate reduction of IR.

 

Despite all the faffing I went through I tend to just use my Deben max pro with the deben IR filter clipped to it - it's just more convenient having something that easily clips on, on a dedicated lamp which comes with a nice bracket to fix it to a scope. The handheld trigger mount for this lamp means you can switch over simply.

 

I still have the IR "cannon" but to be honest the NV I have doesn't need that kind of range, 100-150 is all it needs and the deben does this perfectly.

John you were right to start but you just need an IR Filter for your lamp.

 

Taken from this site.

 

"As soon as the hotmirror filter is removed immediately replace it with the infrared filter to avoid any dust settling on the sensor."

 

Infrared filter prices here.

 

That's the process needed unless I'm mistaken? If so I'd like to be corrected as I'd buy a camera otherwise but to add $145 makes it too expensive for me.
