I've had the problem with the dome on the uwl-h100 fogging up when getting in the water before, usually just waiting a bit with the lens in the water would sort it out as the glass cooled.
Today I had the problem that the inner wet lens was fogging up, which took much longer to cool down as it is not exposed directly to water.
Any idea how I can prevent this from happening? I'm assembling the lens in a well air conditioned room...
I had similar problem. I got the fog on the internal surface of the dome or front lens under the dome glass. I was trying different techniques including mounting the dome in a special environmental chamber
At the end I did this in the car, so first I setup max heating with internal flow of air .... after some time, when temperature became uncomfortable I switched air-condition to max cooling .... when it became cold then the air should be dry, so I attached the dome on the lens.
After that there was no more fog inside the dome even when I did diving in cold water.
