Ball Lenses
Product Information
Polished ball lenses are produced by a
mechanical machining process. Due to
the high flexibility of the process the ball
lenses are increasingly used as pre-forms
for the precision molding process. The
surface and geometry of each ball lens
has an optical quality and can therefore
also be used as an optical element.
