Method and apparatus for making a high resolution light pattern generator on a transparent substrate |
摘要 |
A light pattern generator that can be used to form a gobo for use in a projection optical system. A transparent plate is coated with a stack that is absorptive and reflective. The stack is formed to be ablatable in the form of a pattern. The stack can have multiple different layers with multiple different characteristics, all of which are ablated by the laser. |
