Product Description
C125M MWIR Cooled Infrared Detector

Mid Wave FPA 128×128 / 25μm MCT Cooled Infrared Detector

The C125M MWIR is a cooled thermal imaging detector. It combines a maintenance-free 128×128 IDDCA with a miniature Joule-Thomson cooler.

The C125M MWIR fully satisfies the requirement for thermal imaging and very short cool-down time to ensure efficiency.

Frequently Asked Questions
1. What is a cryocooler used for?

Cryocoolers are machines that keep sensors extremely cold so that thermal images can be taken on long-term missions. In many high-end applications, the sensors that capture images require extremely low temperatures.

2. What are the main factors to measure the quality of a cryocooler?

Long battery life and reliable operation are the main factors to measure the quality of a cryocooler. SensorMicro cryocoolers have a wide operating temperature range and excellent reliability. Their MTTF (Mean Time to Failure) has reached 10,000 hours, which meets 24/7 boot operation requirements.

3. What is MTTF?

MTTF (Mean Time to Failure) measures a part's reliability. It shows you how long, on average, a part lasts before it breaks and you have to replace it. On a basic level, it tells you about the quality of the parts you're buying. The longer they last, the more value you're getting from them.
