Is the clear resin transparent enough to make a prism?


If you polish it up — like in Craig’s write-up of his monocle, here — you can get really great results. In general, though, after removing and rinsing, clear has more of a translucent quality.

Inexpensive glass optics, lenses and mirrors and prisms, are readily purchased in an unimaginable range of shapes and sizes. And no matter how cheap the optics, glass is always going to be better than the resin. If you need optics inside some part of your model, my recommendation is that you look for a way to construct the object in two pieces, and you insert the glass component and then bond the two pieces together with a little resin and some sunlight… you probably only need to hold the parts together for a few minutes in the sun.
