Default Design LCD Loupe for 38 x 50 mm Screen

Can someone point me to information about how to design a LCD loupe to fit a 38 mm x 50 mm LCD screen. The screen is conveniently located in the lower left corner of the camera back. There is a standard tripod mount left of center which I could use to attach an aluminum base plate to support the hood. What I am interested in is a discussion of how one comes up with an appropriate loupe lens (I've seen manufacturers argue that good quality magnification requires a triplet lens) and then calculates the proper distance from the LCD screen to the lens. I am confident I can construct the hood if I have the proper parameters.
