2.8.1
Blocking demo lenses (use the small-diameter lens holder)
■
When blocking demo lenses before tracing them, mark the lenses with a lensmeter beforehand.
■
When blocking demo lenses, it is unnecessary to load lens shapes, enter processing conditions
and layout data.
1
Select Demo lens for the lens type from
the Layout screen or Blocking screen.
2
Place the small-diameter lens holder in
the center of the lens table.
1) Lift the blocking lens clamp lever
upward.
2) Place the small-diameter lens
holder in the orientation as shown
in the figure on the right and fit the
three holes of the small-diameter
lens holder into the three fixing
pins of the lens clamp.
Slowly lower the lens clamp lever.
3
Set the lens cup with the double-coated adhesive pad to the cup holder.
For details, see “2.8 Blocking” (page 95).
• For the demo lens, when the lens cannot be hold with the three pins as the lens is small,
use the small diameter lens holder.
• If the lens is large enough to be held with the three pins of the lens table, clamp the lens
with the normal lens clamp without using the small diameter lens holder.
For details, see “2.8 Blocking” (page 95).
