The ZS series was previously a zirconia slurry abrasive designed for soft glass lenses.

However, with the introduction of the new ZSH-7000A, polishing of hard glass materials is now also possible.
It delivers a superior surface finish compared to conventional zirconia slurries and cerium-based abrasives.

ZSH-7000A　★For Hard Glass★

Typical polishing power follows the order of
1100A＜2000C、2100C＜3000A
Please note, however, that actual performance may differ or even reverse based on the specific glass type and polishing parameters.

While performance varies by product,
each one is designed to eliminating issues with lens surface quality.
This allows to reduce overall polishing time.
