Magnifying Loupe

The magnifying loupe allows the user to view the screen of a digital camera (or any flat object) at a closer distance than normal and thus the image looks larger so more detail can be seen.

The openSCAD program generates stl files for a number of pieces which when assembled with a lens completes the loupe.

When the loupe is to be used with a digital camera, it generates stl files for four pieces. The sizes of the pieces depends upon the screen size specified, the lens diameter, thickness, and focal length, and the length of the bracket to attach the loupe to the camera tripod socket. If one doesn’t want to attach the loupe to a camera, but just use it as a magnifier, then you don't need to print the bracket

For my prototype loupe I used a 19x67 meniscus lens that I had purchased from Edmund Optics. The first number is the diameter in mm and the second number is the focal length, also in mm. In order to get a sharp image in the corners, one should use a lens whose focal length
