S-KING Core of Proprietary Optical Axis Alignment Technology

  • Curve fitting technology and abnormal data screening 一一Fit curves based on collected data and enable abnormal data screening to deliver more accurate fitting results.Interference data correction and elimination.
  • Process or eliminate interference data in the system through hardware and software, mainly addressing anomalies in the optical path system such as light source energy fluctuation, stray light interference, four-quadrant stability, stress-induced birefringence, and unstable polarization state.

Curved Film Preheating Forming Technology

  • Ultra-precision mold machining and polishing, with surface roughness up to 2nm.Mold temperature control ranges from room temperature to 200℃, cavity vacuum ≤10Pa, and lamination pressure 1bar~20bar.
