Green optics
Dichrioc mirrors (LEO DRX-1064/532-45P-UF-2038; HR for 1064nm and 532nm) for in-air periscope and harmonic splitters (LEO LWP-45-R532-T1064-UF-2038; HR for 532nm and HT for 1064nm) for in-air use were brought inside the mine. They are now stored at the PSL desiccator, together with dichroic mirrors (by Sigma-koki) for in-vac use. Other optomechanical components are also stored at PSL room (see Photo1).
How to make in-vac picomotor cable
See attached Photo2.
Dsub male pins are swaged to picomotor side, and female pins are swaged to Dsub 9pin side.
Male pins and female pins have different hole size. So, use dial B for male pins and dial A for female pins.
Swaging should not be done at the edge of the pins. Therefore, you have to slightly pull put a pin from the swaging tool before actually pressing the pin.

A part of these green optics (Dichrioc mirrors (LEO)*2, harmonic splitter (LEO)*1) for in-air, and in-air periscope-set were brought to Yend for TMSY with Michimura-san's permission.

These green optics (Dichroic mirrors (LEO)*2, harmonic splitter (LEO)*1) for in-air were returned to PSL decicator.
The 2 dichroic mirrors were unpacked in TMSY clean booth once.
I noted this on the box of the mirrors.
(Periscope is used on TMSY optical bench.)
On the other hand, two dichroic mirrors for in-vac (by Sigma-koki) were brought to TMSY booth and were installed in BRTY chamber.
