In order to remove the infrared filter, we had to figure out how to take apart the JB-1 camera. We were pretty sure the camera was not glued together as we could see the seams flex open when we gave it a little pry with the screw driver. After a little poking we discovered that the camera was held together by just one screw...underneath the label at the bottom.
Once the screw was removed, the camera was easy to pry open. Some care had to be take to not break the tabs. Small flat head screwdrivers were very helpful in this effort.
Once the cover was removed, it was easy to see what had to be done. The circuit board was mounted in such a way that the CCD and lens assembly was facing up. This meant it did not have to be removed from the housing for us to get at the lens.
Upon closer inspection, both the lens and the lens mount were glued into place (red arrows). The small dabs of glue will need to be removed before we can go any further.
The glue was actually easier to pick off than we had anticipated. We used the tip of an x-acto blade to flick off the clumps. Once the glue was removed, the lens unit lifted off with no problem.
With the lens assembly removed, we could now see clearly the CCD sensor array...hmmm, where is the IR filter?
Unlike Zack's project, the JB-1 did not have a separate IR filter. The IR filtering was done by a coating which was on the lens itself. This meant we had to scrape the coating off.
