Production processes

Fire processing:

We manufacture quartz and borosilicate glass with various burners and lathes.

Grinding, polishing, welding processing:

We optically polish with fine abrasive sand after grinding.

Machine processing:

We cut glass plate with glass cutter etc.

Activated decomposition of deuterium lamp:

We remove impurities from the filament before filling deuterium gas into the lamp.

Discharging gas from deuterium lamp:

We discharge extra gas and impurities from the lamp during lighting the lamp.

Chipping off deuterium lamp:

We chip off the lamp from the pumping machine after filling deuterium gas into the lamp.

Assembling the electrode of hollow cathode lamp:

We connect the lamp bulb to the electrode with fire processing.

Setting hollow cathode lamp:

We set the lamp onto the pumping machine to degas from the electrode.

Pumping hollow cathode lamp:

We degas the electrode and remove impurities.
