Ultra-Stable Optical Reference Cavities for Precision Research | SNP Optical

High-Performance Optical Reference Cavities for Quantum Optics, Atomic Clocks & Laser Stabilization

Engineered for thermal stability, ultra-low vibration sensitivity, and unmatched reliability in critical research environments.

Why Choose Our Optical Reference Cavity?

If you're working on experiments where even nanometer-level instability could compromise results, our Optical Reference Cavity solutions offer the precision you need. Designed for quantum computing labs, gravitational wave observatories, and next-gen atomic clocks, these cavities maintain <0.5 ppm/K thermal stability while resisting vibrations up to 90% better than standard models.

Key Advantages

• Thermal Stability: ULE® glass and Zerodur® spacers minimize drift (<1 kHz/day), ensuring laser frequency remains consistent in quantum communication satellites and atomic clocks. This stability resists temperature swings, critical for maintaining precision in orbital environments or lab setups with varying heat.​
• Vibration Resistance: Proprietary isolation tech reduces sensitivity to <1e-10 g/√Hz, shielding gravitational wave detectors and industrial metrology tools from external vibrations. This minimizes noise, ensuring accurate measurements even near machinery or in seismic-active regions.​
• 5-Year Reliability: 99.999% mirror reflectivity with hermetic sealing against contamination, ideal for long-mission satellites and industrial lasers. The seal blocks dust and moisture, preserving performance in harsh environments where maintenance is difficult or impossible.​
• Custom-Built: Specify wavelengths (380-2400 nm), FSR, or form factors for unique setups, from compact quantum sensors to large interferometer mirrors. This flexibility ensures perfect integration, optimizing performance for specialized applications like gravitational wave detection.

Where Our Optical Reference Cavity Excels

• Atomic Clock Development: Achieve sub-Hz laser linewidths for ultra-precise timekeeping, leveraging ULE® glass and Zerodur® spacers to minimize drift below 1 kHz/day. This stability ensures time measurements stay accurate over decades, critical for global navigation systems and fundamental physics research requiring temporal precision.​
• Quantum Communication Networks: Stabilize entangled photon sources with <1e-15 frequency stability, using vibration-resistant tech (<1e-10 g/√Hz sensitivity) to shield against environmental interference. This preserves photon entanglement, ensuring secure data transmission in satellite and terrestrial networks where signal integrity is non-negotiable.​
• Space-Borne Gravitational Detectors: Radiation-hardened variants survive launch G-forces and orbital thermal swings, with hermetic sealing to block cosmic dust. Their thermal stability and low vibration sensitivity enhance detection of faint spacetime ripples, vital for studying black hole mergers and neutron star collisions from orbit.​
• Field-Deployable Spectroscopy: Compact models (Ø50mm) include integrated damping for truck-mounted systems, resisting vibrations from road travel. Custom wavelengths (380-2400 nm) and rugged design ensure accurate material analysis in remote locations, from oil fields to environmental monitoring sites.
