Where to buy IR Infrared Filter - internal???

[yuriyo923]

I'm looking to convert one of my camers to IR (myself) and was wondering if anyone knows where I can buy a glass IR filter?

I know lifepixel sells them, but $145 for little filter is a little too much.. Some people have been cutting them from lens filters (like Hoya R72) but thinkness is not the same...

Can onyone help? Thanks!

i have seen tutorials on how to do it yourself but id never trust myself to do that work. best bet is to send it away. i really dont mind the filter approach. i really dont have cash for a second body

I know you should remove the AA filter from the sensor on some cameras, but I thought the actual IR filter went on the lens. I could have misunderstood though. If you've got steady hands and proper tools I don't see the removal to be that difficult.

This seems like a good site for the instructions: http://www.lifepixel.com/IR.htm

Thanks for the links.. I have done it before.. i screwed up 2 Rebels before I got it right :) but I wanted to know where I can get a glass filter...

There on the sight under Order now: IR filters-Clear Filters-replacement original filters.

It would be best to do a google search for 'schott rg715' (assuming you want a 715nm filter). You can buy the filter glass in 2" square. Not sure which camera you are planning on converting but you'll get at least 2 filters from one of these.

It is very high quality and should be a lot cheaper than the lifepixel

I've always wondered how it is that using an externel R72 requires long exposure times, yet putting the same filter internally instead of the body's IR filter magicly reduces the exposure times to "normal"
anyone know why this is?

The Luminous Landscape took a long look at IR imaging (http://www.luminous-landscape.com/reviews/cameras/infrared%20dslr.shtml) and included a link to a mail-order source for filters. (http://www.maxmax.com/aXNiteFilters.htm)

When you convert the camera and use an internal filter, you are replacing the IR blocking/AA filter inside the camera. If you use an external filter on an unmodified camera, the IR wavelengths are being passed by the external filter and blocked by the internal filter - hence the long exposure times.

The link to 'mail-order' is to maxmax. They do camera conversions and brand their filters xNite. The glass is manufactured by Schott so the OP may as well go and source the original product. Cuts out the middleman and saves some money. I assume that is what he is trying to achieve

thanks - guess I really didn't put too much thought into the process! (doh!)

Awesome... Thanks Wayne! I think this is just what I've been looking for! The original IR blocking filter on 300D is 2.5mm think and I found one that is 2.5mm think.

Thanks!

Try Jim Chen. I shoot with him occasionaly.
He did the full time IR mod on my XT.
Very happy with the work.
Less than Life Pixel.

Tell him I sent you (no kickbacks etc...just like him to know I liked the job he did so much I wanted to let others know).

Hmm...I work in the lab at a glass company, I'll have to see if I can make a homebrew IR filter. :D

I've had lifepixel do two camera bodies for me, a 10D and a 5D and they do a great job of it but you are right that they are expensive. There are plenty of directions on the net on how to do this but I haven't seen many pitching the physical parts required. I still feel justified in the extra cost to have them do it all, I am just not that mechanically inclined. I can always take something apart, then comes that nasty part about re-assembling it.
