Opto-Line uses the following methods for our customer’s custom Multi-Density Resolution Masks:

Half Tone:

By using very small dots and changing the amount of the dots, we can create varying densities that typically fulfill our customers’ needs.


Discrete, individual depositions of Inconel are used to create each density. In this case, Opto-Line requires separate and distinct areas for each transmission level.
