Optics
can be found virtually everywhere, from fiber optic couplings
to machine vision imaging devices to cutting-edge biometric
iris identification systems. Despite the many applications
that depend on optics, most of our customers are not optical
engineers. As a result, they require aid in specifying the
correct optical components for the mechanical, electrical,
and various other existing applications.
After
a design is successfully completed, we can determine the characteristics
of each optical surface in the system and tolerance them according
to manufacturing capabilities. This is done with an emphasis
on the value and uniformity of the shape, as well as on the
cosmetics of each surface. The maximum allowable deviation
of an optical surface from a perfect surface is described
by Surface Accuracy. There are several terms associated with
accuracy, as follows:
Surface
Quality
Surface
Flatness
Surface
Accuracy
Centration
Prism
Angle Accuracy
Thickness
EdgeTreatment
Bevels
