SQUARE WAVE patterns (Ronchi and Gratings) have extremely sharp edges. This sharpness is achieved through our unique manufacturing capabilities and processing technologies which generates the sharpest edges available anywhere. Whereas the APPLIED IMAGE SINE Sinusoidal wave patterns use continuous graduation of density.

Using our unique semiconductor processes, we can provide these patterns on a wide variety of substrate materials and sizes including glass, plastics, and papers.  And for those unusual applications requiring specialty materials, our sales engineers are prepared to assist you with your exact needs.
