• What is a cryocooler used for?
  Cryocoolers maintain extremely cold temperatures for sensors to capture thermal images during long-term missions. Many high-end applications require these low temperatures for optimal sensor performance.
• What are the main factors to measure cryocooler quality?
  Long battery life and reliable operation are primary quality indicators. Our cryocooler features a wide operating temperature range and excellent reliability, with MTTF reaching 10,000 hours to meet 24/7 operational requirements.
• What is MTTF?
  Mean Time to Failure (MTTF) measures part reliability by indicating average lifespan before replacement. Longer MTTF values indicate higher quality components and greater value.
