Spots on the LCD Screen

If you have inactive spots on the LCD screen in your infrared camera’s monocular viewfinder, they are probably caused by sun damage.

When working outdoors, sunlight can easily enter an upturned viewfinder eyepiece. When this happens, sunlight can be magnified by the viewfinder optics permanently damaging or destroying your LCD screen.

To prevent such damage, always cover your imagers eyepiece to prevent sunlight from entering the viewfinder. Temporarily placing a cover such as a baby sock over the eyepiece until you are ready to image can help to avoid a ruining an expensive viewfinder.
