Leybold Optics (Cary, NC) is now offering direct monitoring on box coaters with planet (double rotation) configuration. Optical monitoring is used in optical thin film production, in addition to the conventional quartz crystal measurement. The monitor glass is located in a holder, which is fixed on the sun wheel and moves in single rotation. The radial position of the monitor glass is close to the radial position of the planet axis, which is about 300 mm out of the center. The transmittance measurement on the monitoring glass correlates to that of the dome-shaped calotte. The new monitoring system is available for wavelengths from UV to IR. Photonics West Booth #2411
