Frequently Asked Questions
What is a cryocooler used for?
Cryocoolers maintain sensors at extremely low temperatures to enable thermal imaging during long-term missions. Many high-end applications require these ultra-low temperatures for optimal sensor performance in image capture.
What are the main factors to measure the quality of a cryocooler?
Long operational lifespan and reliable performance are primary quality indicators. Our cryocoolers feature a wide operating temperature range and exceptional reliability, with MTTF (Mean Time to Failure) reaching 20,000 hours to meet 24/7 continuous operation requirements.
What is MTTF?
MTTF (Mean Time to Failure) measures component reliability by indicating the average operational duration before replacement is required. This metric provides insight into part quality and long-term value, with longer lifespans delivering greater operational value.
