Ultra-High Intensity Imaging
Photochemical milling has advanced quickly in
the past three decades. Early machines useful in
the photomechanical phase of the process used
low intensity light sources to resolve a limited
range of features. As the features required in the
finished product increased in complexity new
equipment has been designed to meet this need.
Today’s most capable imaging units have the
ability to produce very high levels of UV light,
image fine features, and provide adequate cooling
to the exposure area. They are easier to operate
and are more reliable than ever.
