A method of planarizing a plurality of orientable non-spherical flakes supported by a longitudinal web is disclosed. A web supporting a coating of field orientable non-spherical flakes is placed between magnets so that the fields from the magnets traverse the web. First and third magnets are provided on one side of a feedpath and a second magnet is provided between the first and third magnets on the other side of the feedpath. The first and third magnets have a same polarity and the second magnet has a complementary polarity to the first and third magnets, so that a first magnetic field spanning the feedpath is present between the first and second magnets and second magnetic field spanning the feedpath is present between the second and third magnets, wherein the magnets are positioned so that a plurality of non-spherical field orientable flakes moving along the feedpath experience a first rotation as they pass the second magnet during relative movement between the web and the magnets; The web is then moved through the fields passing the magnets and the coating is subsequently cured.

An optical spectrometer uses a tapered Fabry-Perot type variable optical filter in conjunction with an optical detector array. The filter can be a long-pass, short-pass, or narrow bandpass filter. The stability of the variable optical filter allows high resolution, depending on the number and spacing of the detectors used. In a further embodiment, signal-processing techniques are used to enhance the resolution of the spectrometer beyond the measured response.

A high ratio planetary drive system, a vacuum processing chamber system incorporating the planetary drive system, and a method of operating the system are disclosed. The planetary drive system provides relatively slow planetary workpiece rotation for effecting processing (deposition and reaction) of thin films, in particular, optical thin films, with complete film oxidation, controlled film uniformity, reduced bearing wear and reduced heat dissipation.
