calcite polarizer on IOT2L prepared
[Cheryl, Chris, Kiwamu]
This morning we have prepared a calcite polarizer (SN#2) which will be installed in the IMC_REFL path on IOT2L. Right now it is put aside out of the main path and will be installed tomorrow.
And we installed the calcite later yesterday (Tuesday). It seems working fine -- it creates P and S polarizing beams as expected. We also installed a HWP in front of it to allow us to adjust the amount of S-polarization propagating through the calcite.
