Hi Prof i cant find the build specs for the housing (BOX) only where to get the prisms in AU. Cheers
I don't think any specs for the housing was published..
It will of course depend on the size of the prisms..
If the prisms you refer to are the ones used in Marks earlier models, then I can pass on the dimensions of my housing to you..

Re: Making A DIY Anamorphic Lens

You only need to blackout the thick end of the prisms..

My original prism ends were blacked out with flock tape, but the backing on the tape actually reflected the image!
If you looked at the lens from the side, you could see a reflection of the image!!

I removed the flock tape and painted the ends with a special matt black glass paint..and I would recommend that you use a similar product..
It's a 2 pack application..consisting of a glass primer and a carbon black fluid acrylic..
This product is available from Artists supplies..The brand I found was Jo Sonja's..which I bought online..
