There were some homeworks left from the last March; see here.

Optics name	Type of the optics	The holder	Note
1st steering mirror -> STM3	Newly opened "CVI HM-2037-45"	Polaris-K2S1 + washed but not vented M4 screw + ME-KAGRA-1704107-A-DWG	I determied to leave the M4 screw without a vent hole, as there is a groove on the pedestal. The outer diameter of the optics was wiped to remove the pencil memo. The original one (TFVMQ-50.8C10-20-W1D-532/1064-ARS-30/40D) was stocked in the desiccator as of 20190205
Harmonic BS -> HBS	HBSY21	Polaris-K2S1 + washed imo M6 screw + OptoSigma VRO-12-100 + VRS-12-100 + VBSP-40100
2nd steering mirror -> GST0	Newly opened "TFMQSP-50.8C10-20-532/1064-0/26D"	Polaris-K2S1 + washed but not vented M4 screw + ME-KAGRA-1704107-A-DWG	I determied to leave the M4 screw without a vent hole, as there is a groove on the pedestal. The outer diameter of the optics was wiped to remove the pencil memo. The original one (TFVMQ-50.8C10-20-W1D-532/1064-ARS-30/40D) was stocked in the desiccator as of 20190205
Collimation lens for green (3rd BRT lens for green) -> BRT3	SLB-50.8-200NM	VLHG-50.8 + washed M6 imo screw + OptoSigma VRO-12-100 + VRS-12-100 + VBSP-2460	VBSP-2460 should be replaced to VBSP-40100 later.
