Design Considerations for Improving
ESD Performance
The flange on the lens has been
designed to increase the creepage
and clearance distance for elec-
trostatic discharge. The table on
the right shows typical values
assuming base plate construction
per the Agilent supplied IGES file
and HDNS-2100 lens flange.
For improved ESD performance,
the lens flange can be sealed (i.e.
glued) to the base plate.Note that
the lens material is polycarbonate
and therefore, cyanoacrylate-
based adhesives or other
adhesives that may damage the
lens should NOT be used.
The trimmed lens, HDNS-
2100#001, is not recommended
for corded applications due to the
ESD spec requirement.
