The SA-430F5 is a preamplifier for submicro-signal detection, which has been developed to assure noise reduction never before accomplished. The SA-430F5 is used to foster versatility as a sensor head amplifier or preamplifier for sensitivity improvement and noise reduction in analyzers and measurement instruments.

Applications:

  • Superconducting device in quantum computers
  • MCT (Mercury Cadmium Tellurium) sensor for infrared detection
  • Squid sensor for micro-magnet detection
  • High-temperature superconducting Josephson device for microwave detection
  • Electromagnetic sensor for MRI systems
  • Photodetector such as a photo-multiplier and photo-transistor
  • Improving sensitivity of lock-in amplifiers
