so earler today i found my self trying to get the infrared filters that had failed epoxy, so i took the assembly out of the laser an soaked in my favorite toxic solvent Toluene, after a while the first one failed, it cracked so i let the second one soak longer and to my luck it popped of with little effort and started the task of removing and buffing the bad glue off, i taped the 5mm x5mm smurf colored filter on sticky tape so i would not lose it, after a successful buff i moved it to clean tape and to a clean buffer wheel for the dremel but the filter was gone, i looked high and low and being a mild horder this took some time and taking my recliner apart, cleaning the floor, the chair net to this one, still no little filter glass. so about 4 hours go by and my trash bag is full and i found all kinds of things that whent missing into the chair. I even inlisted the help of a friend to give me motivational jokes and other things around the house, about 4 hours have now passed and i moved on to another project and happened to notice a bandaid on my arm now had a little blue square in the middle, after exerting the effort some spend on trying to find big foot my little filter was with me the whole time. all that effort, all of that cleaning and it was with me the whole time clung to my arm. oh well i can at lest see my floor now, one down and 2 to go. i think when i get new filters i will just tape them to my self, they will be safer
