Zerodur Super Stable Cavity-Square Cavity

Engineered for labs demanding nanometer-level stability, the Zerodur Super Stable Cavity-Square Cavity combines near-zero thermal expansion with precision geometry to eliminate drift in critical experiments. Trusted by leading institutions like LIGO and ESA, these cavities ensure repeatable performance in atomic clocks, quantum sensors, and interferometry systems.

Why Choose Our Zerodur Cavities?

✅ Zero Thermal Drift: Made from Schott Zerodur® (±0.005×10⁻⁶/K CTE), maintaining shape across -30°C to 80°C, ideal for aerospace sensors and industrial lasers. This stability prevents dimensional shifts that could disrupt precision, ensuring consistent performance in polar expeditions or desert factories where temperature swings are extreme.
✅ Laser-Ready Surfaces: Sub-nanometer roughness (<1 nm Ra) minimizes optical loss for UV to IR wavelengths, critical for quantum communication and medical lasers. The ultra-smooth finish reduces scatter, preserving beam integrity in dermatological devices or fiber optic networks where signal strength directly impacts results.
✅ Stress-Optimized Design: Square geometry reduces mechanical strain vs. cylindrical alternatives, enhancing durability in high-vibration environments like vehicle-mounted LiDAR. This structure distributes force evenly, preventing cracks in rugged setups such as construction site scanners or military field equipment.
✅ Custom-Built: Modify size (10mm–200mm), coatings (HR/AR), or mounting interfaces in 8–12 weeks, fitting unique systems from lab spectrometers to satellite telescopes. This flexibility avoids lengthy redesigns, ensuring seamless integration without compromising performance or project timelines.

Where It’s Used: From Lab to Space

Atomic Clocks: Reduce microwave Zerodur Super Stable Cavity-Square Cavity drift in optical lattice clocks using Schott Zerodur® with ±0.005×10⁻⁶/K CTE, ensuring consistent cavity dimensions across temperature fluctuations. This stability minimizes frequency errors, critical for maintaining timekeeping precision within nanoseconds over decades, essential for global navigation systems.
Quantum Computing: Stabilize laser frequencies for qubit manipulation via sub-nanometer surface roughness (<1 nm Ra) that reduces optical loss, preserving beam coherence. The ultra-smooth surfaces prevent frequency jitter, ensuring accurate qubit state control—vital for error-free quantum calculations in next-gen computing systems.
Gravitational Wave Detectors: Minimize thermal noise in interferometer mirrors through stress-optimized square geometry, which reduces mechanical strain and heat-induced vibration. This design enhances mirror stability, allowing detection of faint spacetime ripples that would be masked by thermal fluctuations in less robust components.
Satellite Lasers: Ensure alignment stability in orbital temperature swings with Zerodur®’s thermal resilience (-30°C to 80°C) and custom mounting interfaces. This combination resists dimensional shifts from extreme temperature changes, maintaining laser pointing accuracy for satellite communication and Earth observation missions.
