Step 2Unscrew the lense assembly
unscrew the lense assembly from the circuit board. When you unscrew this, the CCD (the Charge Coupled Device is an array of photosensors on the green PC board) will be exposed.
Side Note:
I'm not sure but I think maybe the CCD can be harmed if you shine bright light directly at it (without a lense assembly in front of it) so I hid it away under a piece of paper while doing the rest of the steps.
Pull the lense assembly out from the surrounding knobby thing (the blue ring that you turn to adjust the focus)

best of my knowledge you cant damage the ccd array with indoor light. Not sure about direct exposure to UV though

Uv won't hurt it, most CCD's have a glass lens on the chip protecting it from the enviroment and shortwave UV at the same time ( Quartz glass is hard to get in optical grade ) and if you really want to look at uv though you need to etch the back side of the CCD with hydrofloric acid and then flip it over to use it ( most CCD's suck with Blue and UV responce ) And yes they are makeing them like that now for flame sensors.
