WANTED  Ir filter






Check out stevetexas' post regarding the IR filter in the toothpaste cap idea he came up with - he posts a link to where he bought the inexpensive filters...

G !
 
Senkat have you ever tried getting an IR filter from a webcam? Is there really one in there?
 
The only one I tried was made of glass, and I had no way to get it off of there !
I have heard they are on most webcams - Just have not tried that is all. Just PAY THE $12 man !!!

hey, I looked at the link and there are a bunch of diffderent ones which one do I get?
 
Get the IRC-21 !! It absorbs the IR, rather than reflecting it which could be disastrous !
 
I dunno what size/quality you need, but if you want a quality 1cm square from Coherent, send me a PM. (its gunna cost a little more than that other filter, but it'll be a hell of a lot cheaper than from coherent)
 
Re: WANTED  Ir filter

It sux that the IRC30's have a much better curve and better transmittance but are only available as reflective filters. I would grab one, but I have no need for a reflective one.

just rip one out of a webcam! i made a vid showing the effect of a ir filter out of a webcam here: http://youtube.com/watch?v=neIMzd_K90E it's using the pump diode out of a DX 20, so there is alot of ir, as you can see in the first part. they are about 1cm by 1cm in this camera, but it can go up or down.
 
Re: WANTED  Ir filter

I've got a couple of these IR filters from webcams. I know I have one right in front of me now... but I don't know where the other one hopped off to.. :-? This one is a tiny thing about .5cm square. It's quite thick and has incredible VLT though. It's almost perfectly transparent :D
