Coating

Advantages

• Coating thickness along resonator hemisphere – 100÷300 Angstrom
• Coating thickness non-uniformity – 1 mg
• High adhesion of metal layer to quartz
• High resistivity to temp. impact when soldering
• Impedance control while coating
• Minimum stresses and damping induced by metallization
• Emergency automatic shutdown vacuum system
• Capability – 2 quartz parts per shift
