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. |
Harmonic BS -> HBS |
HBSY21 (From NAOJ for this purpose) |
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. |
Collimation lens for green (3rd BRT lens for green) |
SLB-50.8-200NM (From NAOJ for this purpose) |
VLHG-50.8 + unwashed M6 imo screw + TR75V/M + PH75V/M + washed M6 screw + BA1V/M (all from NAOJ) |
The VLHG-50.8 required M6 imo screw!!!!!!; need a proper tool to tighten the PEEK retainer of VLHG-50.8; there is a memo in the mirror's outer diameter and need to be erased for vac compatibility. |
