Cute, not sure about the colour scheme though ...
I realise this is all practice stuff for you. How would you feel about making something small and useful ?
I have a requirement for a small 44 mm x 44 mm 'cube' as a positional element in a beam splitter I'm working on. No stress loading just an accurate support device.
Design is quite simple basically being a cube with hollow 'cube' inside which puts the quad prism into alignment with the optical axis.
I've proved it works with my experiments, now I need to make a proper assembly for it.
Let us know anyway. Happy to pay material costs and whatever within reason. Preferred colour is black if possible btw
Something to get your teeth into ...
Cheers
Brent
