What is 3DII?• Multi-mode spectrograph
--- includes Integral field spectrograph (IFS) mode,Fabry-Perot mode, etc.
• Optical wavelength (360-900nm)• Now used at Subaru Cassegrain Focus

At UH88:June 2002
At Subaru:August 2002
In the case of Cassegrain

Purposes of 3DII + AO188
• First optical instrument used with AO at 8-10m class telescopes
~0”.1 spatial sampling of 3DII• Providing evaluation of AO188
in optical wavelengths

What is needed for this?
• Mechanical interfaceNasmyth Mount
Four fixed points• Optical interface
dichroic mirror

Optical interface (dichroic mirror: measured)
cf. Laser guide star 589nm.
AO low-order wave-front sensor 450-1000nm.

Cass or Nasmyth in future?
• Both desiredNasmyth for longer wavelengths
(>650nm)Cass for shorter wavelengths (<650nm)
We would try to minimize our changes of foci.

Proposed schedule
This must not damage AO188, IRCS, Hi-CIAO schedules.
This must not damage Hawaii observatory schedules, including daycrews’ ones.

Proposed schedule
2010/2011
Optical alignment between 3DII & AO188(by using 3DII CCD & AO188 worked)
Software integration with AO188through Gen2 (SOSS compatible)?
Test observations
