OPERATING PROCEDURES : Blocking
2.9.2 Blocking demo lenses
When blocking demo lenses to trace them, mark the lenses with a lensmeter in advance.
See “2.4.3 Demo lens tracing” (Page 35) for details.
When blocking demo lenses, it is unnecessary to call up lens shapes, enter processing conditions and
lens layout data.
1
Set the lens type to Demo.
2
Set the lens cup with the double-coated adhesive tape into the cup holder.
See Step 1 of “2.9 Blocking” (Page 72).
3
Place the lens on the lens table with the lens convex side up.
4
Align the lens.
Align the middle marking with the center of the alignment scale.
Ensure that the markings are level.
5
Block the lens.
The subsequent steps are the same as those in “2.9 Blocking” (Page 72).
z Setting WD
The WD represents the distance between the
longest vertical lines in the middle on the left
and right. Set the WD value depending on the
space between the markings on the lens.
It is also possible to set the WD just before
placing the lens on the lens table and block-
ing the lens.
