Product Performance

Excellent modulation precision: Stokes parameter accuracy error ≤1%, sensitivity up to 0.0005, repeatability 3σ≤0.01, enabling micron-level optical parameter measurement error control. Wide wavelength adaptability: 170nm to 10μm broad band coverage, combined with ±20° ultra-large acceptance angle, can adapt to UV spectrum analysis, infrared detection and other scenarios without component replacement.

Outstanding operational stability: Resonance modulation design without moving parts eliminates mechanical wear; integrated high-stability circuits ensure modulation frequency fluctuation ≤0.1% during continuous operation, with Mean Time Between Failures (MTBF) ≥1×10⁴ hours. Fast response speed: Modulation frequency range covers 37kHz to 100kHz, enabling real-time acquisition of more than 100 sets of Stokes parameter sets per second, meeting dynamic measurement requirements.

Strong system compatibility: Modular structure can be directly connected to Hinds polarization state measurement systems, stress birefringence detection equipment, etc., without additional adaptation modules, reducing debugging cycle by more than 50%.
