Abstract:
This is an excel spreadsheet which summarizes the different post types for the ISC in-vacuum optics.

The general idea is that the beam height is 4", and depending on the optic size and where the optic is placed (directly on the HAM table or on a sled), you need a different post:

- 2" optics on table and 1" optics on sled use the same 2" 1/8 post D1000968;

- 1" optics on table use the "tall" 2" 5/8 post D1200237;

- 2" optics on sled use the "short" 1" 5/8 post D1001116
