Progress in the opt-mechanical design of MIRACLE, MIRMES, MIRHES, SCI

MIRACLE, MIRMES, MIRHES 1st version of optical design completed and estimated total

mass & volume Now 2nd version of optics is under investigation , aiming

more compact design - pick-off location can be slightly apart from the telescope center

MIRMES pick-off is located at the re-image of the fore-optics of MIRACLE-long

MIRHES pick-off is located at the re-image of the fore-optics of MIRACLE-short

SCI Now, no-pickoff mirror compact optical design in the housing oriented vertical

New SCI design
