There are a lot of reasons why one might want to have the sensor in their camera modified. We see it all the time for those who wish to shoot infrared or ultraviolet photography. There are even companies out there who will do the whole process for you. Usually, though, it doesn’t involve stripping off the Bayer filter array. Typically it’s just removing the filter that blocks UV and IR.
Well, for Les Wright at Les’ Lab, just removing the blocking filter on his Raspberry Pi camera wasn’t enough. he wanted all the raw data, without any colour interference at all from every pixel on the sensor. So, he went on a mission to figure out away to remove it without killing the sensor. Ultimately, the best method proved to be to burn it off with a laser!
