!!Other Conclusions
* Reflective layout now requires a folding mirror; in previous layouts FTT beam is probably occulted by AAS beamsplitter
* OAP off-axis angle ~30 deg is probably ok according to ICOS
* No significant benefits from not respecting AO or future dichroic mount envelopes
* Addition of a negative lens will be considered as a variation on the above layouts
!!New Tasks
All high priority unless stated.
* ADR: Refine selected layouts
* JSY: Query with NMT:
** AAS envelope
** Space to overhang table
** Clearance above table
** M4 position
* ADR: Tolerancing of direct transmissive layout under table bending
* CAH: Request permission and funding to measure Nasmyth table deformation and temperature gradient at AMOS (during next trip to NMT)

!Technical Meeting #6: Optical layout for CoDR
This meeting will take place on at 14:00 on Thursday 3rd June, in Room 911.
!!Agenda
* Impacts of coupling component mounts together (e.g. on a common baseplate)
** With reference to error budgets
* Need for flat folding mirrors
** What factors drive this?
* Selection of layouts and error budgets to present at CoDR
** Variations on selected layouts to present at CoDR (e.g. "telephoto" lens arrangement)
