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)
- The 'swinging instrument fold' versions of this layout are minor tweaks
- Output fold mirror 25 mm 'downstream' away from OAP4
- New coordinate break object to offset the fold rotation point to approx. it's edge point
- Rotation of Inst #2 'config0001b' direction is set to give output gut ray approx parallel to the telescope axis entering the NGAO K-mirror
- Required motion of fold mirror is about 50 degrees (full range) to switch between Instr 1 and Instr 2
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...)
