I designed a holder for 30mm diameter optics that can be installed inside the 2 inch holder of PCI.

The CAD file is in the workstation folder 'PCI holder'. There are 2 versions of this component :

'30mm_holder' was thought to be 3D printed but it might be too dangerous to use during absorption measurement

'30mm_holder_v2' is compatible with aluminium machining. 

The main difference between the 2 is that a slit to install a o-ring to stabilize small length component was replaced by a through hole in the v2.

The part will be manufactured at ATC.

A long cylinder will be 3D printed to be inserted into the through hole.

This holder should be useable for all the 30mm diameter sapphire we currently have (30mm to 120mm length).
