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.
