Mid Wavelength 640x512 / 15μm MWIR Cooled Infrared Detector

C615M MWIR is one of the HgCdTe/MCT cooled infrared detectors developed by Global Sensor Technology (GST). It is with the most popular 640x512 / 15μm spec for almost all possible applications like long range surveillance system, handheld thermal imagers, gas leakage detection cameras etc. Its wavelength, F number and mounting surface can be customized, which are specially designed for the customers’ requirements.

For applications that require compact design, small size and low power consumption, the C615M MWIR cooled IR detector with RS046 detector dewar cooler will be an ideal choice. On one hand, the RS046 cryocooler is smaller in size than RS058, on the other hand, besides the commonly used F4 spec, this integrated dewar cooler assembly also has the option of F5.5 configuration to match the even smaller optics. It is therefore preferred by handheld imager manufacturers.

As a leading thermal uncooled IR detector and thermal sensor module supplier, Global Sensor Technology (GST) has provided the customers with various mature and stable infrared thermal imaging solutions. It’s easier for the infrared detectors developed by GST to be integrated into more terminal products and greatly reduces the cost for customers.

1. What is the difference between uncooled and cooled IR detectors?

There are currently two types of infrared thermal imaging sensors on the market, cooled and uncooled.

Uncooled IR detector operates at ambient temperature. It is based on semi-conductor industry and thus usually can be fabricated in big volume with small size and low cost. Uncooled IR detectors are widely used in portable/handheld/mobile devices.

Cooled IR detectors are packaged in a unit that keeps them at an extremely low temperature which shall be supported by a cryo cooler. They are much bigger, more expensive and less reliable than uncooled sensors, mainly due to the complex cooling systems they require. However, the cooled systems are incredibly sensitive and usually work with long focal length optics to achieve long range mission.

2. 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.
