Reports

• Did fit check of some parts to be used for IMMT1T-ISS optical axis making. The mirror holder is still empty so the IMMT1 transmission beam to the IMMT1T QPDs should have not been changed (but we did not check it).
• Figs. 1 and 2: the outlines
• Fig. 3 shows where the IR beam was. According to Yano-san, in this photo the beam seemed to pass the center of the (no-mirror, empty) holder but in fact this was just due to parallax; the beam seemed going along almost the "designed" line (see a relevant document). This would be consistent what Aso-san did the other day (18487)

Next step

• Glue the dedicated mirror onto the holder, and adjust its alignment to guide the input IR beam for ISS in the appropriate direction.
