  1. Updates on Opt-Mechanical design of Japanese-led FPIs Mar. 27th2010 Hideo Matsuhara

  2. 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

  3. New SCI design

  4. Field-of-Views (updated 11 Mar. 2010)
