Blue Spot On The Image

Postby Polonal » Sat Jul 14, 2018 9:52 pm

Hello,

I was playing with different ways of installing the polarized filter today and everything was fine until later tonight after coming home. When I turned on the camera to try something else I noticed blue spots on the image in the IDE (see Image_01). Tried different things but nothing seemed to work. Then accidentally I noticed that when I put my thumb on the back of the PCB the spots go away (see Image_02). Did I ruin the PCB and now need a new camera? Any suggestions?

Kind regards,

-Alex

No, this would be IR light leaking through the back of the PCB. Just add some black tape to the back of the sensor. A manufacturing screw up lead to 2.5K cameras getting out without the sticker on the back of them to block light from the back of the PCB.
