Summary

Mounts to hold and position fresnel lens and display to determine optimal position (distance of lens from display).

Instructions

I made this to find the optimal distance between a fresnel lens and a LCD display for a FPV headset/goggle setup. Print 2 to hold the Fresnel Lens and 2 to hold the LCD display. I mounted these to strips of cardboard with double sided tape. Screen and lens can also be attached to supports/rigs with double sided tape.
After attaching the fesnel lens and lcd display - secure the lens and supports to a flat surface and place the powered up display (with some type of video feed) on the other side. Position yourself so that you nose is just touching the lens - move the display away and back to find the distance that offers you the best in focus and depth and record/mark this distance.
Reference article on colimated display for gaming/flight simulation that gave me the idea for this (http://www.godrules.net/Fresnel%20Lens%20Collimated%20Display.htm).
