fused silica mirror gluing

Yesterday I tried to glue a fused silica mirror to a mirror holder using a jig as show in attached picture.
I used DP-190 for gluing which was borrowed from Tomaru-san.

This morning I checked the situation of the mirror and it seemed glued to some extent which can be used for foled optical cavity.
The AR side was enough clean.
I will glue another mirror.

[note]
The procedures are as follows:

  1. Apply First Contact on HR surface for protection.
  2. Set a mirror holder and a jig.
  3. Apply glue on the  mirror holder.
  4. Attach the mirror to the mirror holder.
