As demonstrated in the bottom-still left watch, the best is screwed to the edges, when the bottom is glued and held to the sides using splines (or biscuits Should you have a biscuit-joiner).
It is important to acquire two equivalent prisms, considering the fact that the next prism needs to cancel the rainbow produced by the primary prism. If you'll find distinctions within the prism angles, or Should the surfaces are certainly not flawlessly flat, then you're going to get much more "chromatic aberration" (which is able to look like blurring at the edges from the display screen).

After the enclosure is constructed, then you might want to make a decision how to mount it before your projector. In my circumstance, my projector is flush mounted Using the ceiling.

When you alter the angle of the 2nd prism, you're going to be modifying the remaining-edge of the display screen.
1% of the most crucial beam intensity. However, in a very dark theater, even a 0.1% reflection is obvious within the monitor. The majority of these reflections exit from the two ends of your prisms. I just employed black electrical tape to mask the finishes. After Every single prism has a bolt plate glued to the very best and bottom, then it is time to make the enclosure by itself.
