This is a photo gallery documenting the production process of the KAGRA Pre-isolator top filters at Galli & Morelli, Lucca Italy.
It is intended as a complement to the document JGW-T1200804: Standard filter assembly procedures.
It contains process and assembly procedures, comments, and measurements.
Because many steps are the same as in the production of the standard filters, emphasis is put on the differences with respect to what reported in JGW-T1200804.
