QuickCam Team Forums

Hello there!!

I'm here just to tell about my experience on modifying the QuickCam Pro for Notebooks for making it infrared capable...

Opening the camera was very easy... in there I found a little black box:


It has 2 screws and two sold points for the auto-focus system...
I remove them all.
So....inside that box, there was the IR-Filter... it was glued, glued like if it has to support 5 kilograms of weight -.-
I tried to remove it....no luck, I destroyed it....

Well after all, it was off, and all the other parts were ok...
But when I closed the camera, and gave it a try... it was VERY out of focus...
So I tried to understand why... it seems that the IR filter crystal made that the image from the lenses to be "closer"....so I had to CUT...1,5 mm of the plastic box... so it gets closer to the sensor..and, that did the work... hopefully..

I spend many many hours on this one...so, if anyone trys this, it's not going to be easy....

Good luck to all!

Here is someone else who has removed the IR filter off the Pro 9000 too, for astro photo purposes:

But he doesn't explain how he removed it.

@camman -

If you look closely, the image posted above comes from that site.

Please make a note of it.


Thanks.

Actually, that page is fairly clear on this - for telescope use, the entire QuickCamPro lens assembly was removed! The telescope becomes the lens.

Ah, okey. So the "Carl Zeiss Optics" stuff wasn't a selling point for that guy...

But then how did he take images of the same motive with and without IR filter? Is he really using a completely different lens to take the IR-less image? It seemed natural to assume that he removed the IR filter from the original lens.

Anyway, thanks to Rikus we know that it is doable, but not trivial.

He used a separate IR filter on his telescope.

Thanks for all the info above.

I've just taken the IR filter out of my 9000. It's very easy, though I too destroyed the IR filter as it's very well glued in place. I just gently cracked it from the edge and the whole thing broke into 3 or 4 shards.

After re-assembling the focusing distance is about 0 to 15cm. Thankfully this super-macro mode is exactly what i want, but in order to get it back to focusing on infinity the filter could perhaps be replaced with another piece of glass/plastic with the same refractive properties (it's about 1/3 to 1/2 a mm in thickness) to save having to hack away at the plastic casing. Perhaps a microscope cover slide would be about right?

IR sensitivity seems very good.
