High-quality microcrystalline substrate:
The foundation of a highly stable vacuum core Crafted from high-quality microcrystalline materials via advanced integrated molding and bonding technology, our Microcrystalline Ultra-stable Circular Cavity boasts a unique combination of key properties: ultra-low thermal expansion coefficient, high mechanical strength, minimal dielectric loss and negligible outgassing.
These characteristics enable the cavity to achieve and maintain extreme vacuum levels of 10⁻⁸Pa, critical for cold atom physics research and low-pressure optical experiments. As a non-magnetic material, the cavity eliminates magnetic interference, ensuring no disruption to atomic spin states or magnetic-sensitive measurements. The microcrystalline substrate also offers excellent transparency, allowing visual observation of internal processes while maintaining structural integrity. The cavity’s optical windows feature double-sided anti-reflection coatings with transmittance exceeding 99%, maximizing light utilization and resonance efficiency.
Precision circular structure design:
Optimizing performance and integration Our Microcrystalline Ultra-stable Circular Cavity features a precision-engineered circular design with standard dimensions (diameter 50mm-100mm, length 100mm-300mm), optimized for vacuum sealing and resonance stability. The circular structure ensures uniform stress distribution, minimizing deformation under high vacuum and mounting pressure. The cavity is equipped with customizable interface flanges, available in titanium, 304 stainless steel and 316L stainless steel to match diverse vacuum system configurations. The optical windows are hermetically sealed to the cavity body using high-vacuum-compatible adhesives and mechanical clamping, guaranteeing long-term vacuum integrity. The circular shape also facilitates seamless integration with standard optical mounts and vibration isolation platforms, simplifying system assembly and reducing installation complexity.
