The important information is what were used and what should be replaced later.

Optics name

Type of the optics

The holder

Note

1st steering mirror

TFVMQ-50.8C10-20-W1D-532/1064-ARS-30/40D (From PSL room)

Polaris-K2S1 + washed but not vented M4 screw + ME-KAGRA-1704107-A-DWG (all from NAOJ)

The M4 screw needs vent hole; The foot of the pillar is now fixed with a tentative dog clamp, and should be replaced later; there is a memo in the mirror's outer diameter and need to be erased for vac compatibility. The mirror should be replaced with CVI HM-2037-45 (from NAOJ)??

Harmonic BS

HBSY21 (From NAOJ for this purpose)

Polaris-K2S1+ washed M4 screw + TR75V/M + PH75V/M + washed M6 screw + BA1V/M (all from NAOJ)

Nothing special but the post system should be replaced with a fixed height one; to more stiffer one.

2nd steering mirror

TFVMQ-50.8C10-20-W1D-532/1064-ARS-30/40D (From PSL room) today.

Polaris-K2S1 + washed but not vented M4 screw + ME-KAGRA-1704107-A-DWG (all from NAOJ)

The M4 screw needs vent hole; The foot of the pillar is now fixed with a tentative dog clamp, and should be replaced later; there is a memo in the mirror's outer diameter and need to be erased for vac compatibility; actually this mirror needs to reflect only green, so using the dichroic mirror is too much and should be replaced later.

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.

Parts outside of the chamber (in other words, stuffs on the optical table) The naming convention is here.
