SLC windows DO act as a magnifying glass.

StuM5 · Jun 14, 2015

In my original thread on my SLC I mentioned I was seeking a solution for the side windows to aid in reducing the intensity in sun light. See Post #5 of this thread: http://www.gt40s.com/forum/slc-clubhouse/43109-new-sl-c-owner.html
For ease, this is what I said:
“When the sun shines through curvature, at the top of the side windows and strikes me in the head it’s rather intense, almost like being subjected to the sun’s rays as if coming through a magnifying glass.
My understanding is these windows can’t be tinted as they are not glass. Has anyone got any ideas I can implement to prevent this occurrence?

It’s 8am on an a clear sunny winters morning here in Sydney (it was 12 degrees C).
I’m lined up for scrutineering at the race track. I left the drivers door open and attend a drivers briefing. I returned to the car 30 mins later and there was a scrutineer with a concerned look on his face. There was smoke coming out of the cabin of the SLC.
On investigation we could see an intense beam of sunlight on the steering wheel rim, as we watched smoke was pouring off the steering wheel. The curvature of the SLC window does act as a magnifying glass.
This is why on 30+ degree days in Sydney I feel like I’m being burnt to a crisp.

I encourage anyone building an SLC to go test this for themselves; see if you can get a piece of paper to smoke by concentrating the suns rays through the window curvature. Obviously easier to test if you don’t have the windows installed.

I thought this was so unusual that i had to share it.
cheers
