OUTLINE

THE PRODUCTION PROCESS OF

HOYA FILTERS

Each Hoya filter is the result of research, know-how and complete

precision facilities backed by full quality control.

Before production starts, controls are first programmed into a

computer. Then the finest materials are carefully mixed by an

automatic V-blender for absolute uniformity. After being melted with

highly sophisticated equipment, this material is then precision

molded with automatic direct pressing equipment. The pressed

blanks are next slowly and continuously cooled to remove strain,

and are then polished by high-speed, double-surface polishing

machines that assure precise surface quality and perfect flatness.

Next is the coating process which improves the filter light

transmission ability. And the transmission characteristics are

checked by Spectro-Photometer, after which an ultrasonic cleaner

removes all foreign matter from the surfaces. Only after passing all of

Hoya's quality tests are the filters assembled, finished and made

ready for shipment to customers throughout the world.
