Latest Patents

One of McNaughton's latest patents is a method of fabricating diffraction grating masters and the apparatus necessary for this process. This method involves exposing a plurality of reduced first grating patterns on a light-sensitive layer in accordance with a predetermined code. The light-sensitive layer is then processed to produce the first gratings. Following this, a plurality of reduced second grating patterns is exposed on the light-sensitive layer, superimposed on the first gratings, and the processing step is repeated to produce the second gratings. The process continues with vacuum depositing a layer of silver on the superimposed gratings, followed by electroplating a layer of nickel on the silver layer. The resulting nickel-silver layer is then separated from the light-sensitive layer and reinforced for use as an embossing master. A special electroplating fixture is utilized to ensure that the nickel layer being deposited lies flat without 'peeling'.
