640x512 / 15μm MCT MWIR Cooled Thermal Module for Multi Sensor Payload

GAVIN615B is a cooled mid wave thermal imaging module developed by Global Sensor Technology (GST). It consists of a 640x512 / 15µm HgCdTe MWIR IR detector with RS046 cryocooler, hardware electronics and various image processing algorithms are also embedded already to present sharp and clear thermal images.

Configured with RS046 cryocooler, the GAVIN615B is very compact in size, measuring 125x92x67mm in dimension and weighing less than 650g in weight. It’s stable power consumption is as low as 12w. With industrial standard cameralink interface, infrared camera or system integrator can design or integrate their own complete camera easily based on the GAVIN615B thermal imaging module.

- High Sensitivity, NETD≤20mK

- Long Range Detection

- Adjustable Frame Rate

- Easy Integration into the System

The GAVIN615B thermal infrared camera module is widely used many areas such as Remote Monitoring System, Flight Vision Enhancement System, Multi-sensor Payload etc.

1. What are the advantages of cooled infrared detectors?

The cooled infrared focal plane detector operates at a low temperature which is provided by a detector dewar cooler (ddc). It has high sensitivity and can distinguish more subtle temperature difference than uncooled infrared detector. It can detect, identify and recognize objects at a very long range which is more than ten kilometers away. The structure of cooled detector is very complex which results in a relatively high cost than uncooled detector.

2. How does Infrared Thermal Imaging Work?
Infrared thermal imaging system is a passive non-contact detection and identification of infrared technology. It focuses the infrared radiation of the scene on the focal plane array infrared detector through the infrared optical system that can pass through infrared radiation. The thermal detector converts the radiation signal of different intensity into the corresponding electrical signal, and then through amplification and video processing, forms the infrared image that can be observed by the naked eyes.

3. 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.

4. What are the main factors to measure the quality of Cryocooler?

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

5. 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.
