Physical Vapor Deposition (PVD-optics) for Optical Coatings

BEST SOLUTION: Phoenix™ + Eon-ID™ Controller + RC™ Crystal (pdf)

PROBLEMS
< Optical thin films such as MgF and SiO cause crystals to become excessively noisy and/or fail early, preventing completion of deposition run
< Multilayer dielectrics consisting of 50 or more layers exceed the capacity of crystals due to excessive film buildup
< Ultra thin film layers used in “needle” synthesis optical film manufacture are difficult to measure due to crystal rate shock upon opening of the source shutter
< When the shutter on the deposition source is opened, the crystal rate spikes then settles, causing the rate reading to be obscured

SOLUTIONS
< Heating crystals to 90°C allows extended crystal life by reducing stress, thereby eliminating noise and crystal failure, often by as much as 500%
< Alloy quartz crystals significantly reduce film stress leading to low noise, long crystal life
< Temperature measuring instrumentation offers greater process control with knowledge of crystal temperature

RECOMMENDED PRODUCTS
< Alloy quartz crystals (standard AT or the stress-resistant. patented RC™)
< Eon-ID™ Controller or Eon-LT™ Monitor or Controller
