Super Low Loss Spherical Mirror: Precision Engineered for Defense & Aerospace Excellence
When every photon counts, our Super Low Loss Spherical Mirror delivers unmatched signal integrity for mission-critical optics. Designed for aerospace, defense, and high-power laser systems, these mirrors achieve <0.05 dB loss through proprietary thin-film coatings and sub-nanometer surface polishing. Whether you’re optimizing satellite crosslinks or hardening targeting systems against electromagnetic interference, our mirrors combine MIL-SPEC durability with precision that exceeds λ/20 surface accuracy.
Why Choose Our Super Low Loss Mirrors?
- 99.999% Reflectivity: Dielectric coatings minimize energy loss (2–6 ppm) across 632–1550 nm wavelengths, ensuring efficient performance in laser systems and communication setups—critical for applications like fiber optics and spectroscopy where energy conservation directly impacts signal strength and data accuracy.
- Extreme Environment Ready: Operate flawlessly from -50°C to 300°C with radiation-hardened substrates (Zerodur®/ULE®), resisting thermal and radiation-induced damage in aerospace sensors and nuclear facility optics, maintaining reliability in environments where standard components would fail.
- Custom Geometry: Tailored curvatures (SR=500–8000 mm) and rapid prototyping (14-day lead time) allow quick adaptation to unique optical setups, from medical imaging devices to industrial lasers, ensuring precise integration without lengthy development delays.
- Battle-Tested Reliability: Survives 500+ thermal cycles and MIL-STD-810H vibration/shock tests, proving durability in military-grade optics and rugged industrial equipment, ensuring consistent performance through repeated stress that would degrade less robust components.
