Minimal room needed for the prism pair ?

[hobbybob]

Hello,

I am currently preparing my green projector to receive a nice blue diode alongside it.
I have very little space, now to get the blue beam the same height as my green i found a nice 15x15mm square aluminium block.

Only drawback is i have around 15x22 mm left to place the prism pairs, will this be enough ?
I seem to remember they're not that large. Hope someone knows the minimum footprint ?

piece of cake. i built a module a while back that used a 10mmX3.5mm platform.
