[P] Fresnel Lenses

A project log for T^2 TyMist [gd0138]

I need some virtual desktop monitors that offer 90PPD at 90Hz.

Last log, I expected these to come a week ago, but then the package decided to sit in a warehouse for a week.

It's pretty cool. The flat side closer to my eye is the one that allows for a full FOV when the subject and my eye are close to the lens.
I've got no idea why the camera captured all this glare, but I didn't really see it when I looked though. It also looked a tad sharper. I certainly got to see the "screendoor effect" first hand though.

Capturing a section of this test image.

Looking at a monochrome grid such as: 7739449.jpg (1920×1080)I could see that the edges were blurrier than the centre.

What's cool is that none of the rings are visible. It just acts as one flat magnifying glass. I even opened the camera app to see what VR passthrough these days might look like, though my setup was essentially Google Cardboard without the card.

The weight of the lens is 5.8g.
