Optoniks’ primary product, ContourPro 4D, is a system that measures the topographical data of a surface using patented algorithms that remove shadows and allow for the measurement of samples that vary in color and reflectivity.

Companies relying on a Reg D exemption do not have to register their offering of securities with the SEC, but they must file what is known as a Form D electronically with the SEC after they first sell their securities.
