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
