Working files for 102018 interface meeting
Slightly tweeked version of Reni's layout v9
- KNGAO_100mmpupil_120arcsecRelay_100218_v1.ZMX
- Output science fold mirror tilt opened by 5 degrees (from -20 deg to -25 deg)
- Na dichroic moved 'downstream' 50 mm
- Na dichroic tilt opened by 9 degrees (from 19 deg to 28 deg)
- IF dichroic moved 'upstream' 50 mm
- IF dichroic tilt closed by 3 degrees (from 45 deg to 42 deg)
- IF final fold mirror (config 6) opened 3 degrees (from -9 deg to -12 deg) to 'approx' return IF output to similar point
- IF final fold mirror (config 7) opened 3 degrees (from -5.4 deg to -8.4 deg) to 'approx' return IF output to similar point
- Minor refocusing due to change in plane parallel plate tilts (may not be rigorously consistent with each configuration)
Add'l config showing one of our 2nd instrument feed options, an insertable fold after the NGS WFS dichroic
- KNGAO_100mmpupil_120arcsecRelay_100218_v2_short_feed_mirror.ZMX
- Tilted NGS WFS dichroic 'up' out of plane (incidence angle of -40 deg)
- Moved NGS WFS dichroic 'upstream' as much as comfortable (to be 350 mm after 'switchyard' fold)
- Inserted 'removable' fold mirror with incidence angle 45 degrees at location ~ 150 mm 'downstream' of the NGS WFS dichroic
- Note: None of the configurations on this page consider room for the (presumably) 2 different instrument ADC's
Back to Reni's v9, but now with 2nd stage refractive collimator and possible articulating output fold mirror to feed 2 instruments
Again, ADC not shown (would have to assume each instrument handles it's own ADC...)
