Target precision: λ/20
or less
High-precision lapping on large-diameter flat surfaces (about
500 mm in diameter) can be accomplished reliably, reducing the
need for skilled operators.
Pitch surface cutting mechanics enable precision polishing of
large diameters. The granite based conditioning machine (conditioner)
precisely maintains the pitch surface. Using the NC-controlled
cutter, it is possible to make arbitrarily-shaped grooves in the
pitch surface.
Due to the high-rigidity design, which uses a granite table, and
due to the use of a polishing-fluid temperature control system,
overnight operations and repeated stability are possible. |
