The Accelerator for 640x512 / 15μm RS046 MCT MWIR Cooled Infrared Detector Integration
EYAS series cooled AD modules have the pre-amplifier function to convert the analog signal from cooled IR detectors into a digital video stream output. It is available with different resolution formats and different wave bands. EYAS615B is a member of EYAS family with 640x512@15μm MWIR infrared detector and RS046 cryocooler integrated.
EYAS615B AD module features in frame rate up to 120Hz, snapshot, ITR/IWR, windows, anti-blooming working modes. The proximity board comes with EYAS615B makes it an accelerator for OEM customers to carry out fast acceptance test on GST detectors, start rapid secondary development and shorten their development period of modules and complete products based on cooled infrared detectors.

1. What is NETD?
NETD refers to "Noise Equivalent Temperature Difference". It is a measure for how well a thermal imaging detector is able to distinguish between very small differences in thermal radiation in the image. NETD is typically being expressed in milli-Kelvin (mK). Usually the lower the NETD figure is, the higher the thermal sensitivity indicates.
2. What are the key considerations on an infrared detector / thermal module for your application?
---The detector resolution
---The pixel size
---The NETD
---The image quality
---The lens options
---The power consumption
---The size and weight
---The mechanical & electrical interface
---The budget
3. What are the characteristics of cooled & uncooled infrared focal plane detector?
Infrared focal plane detectors can be divided into cooled infrared focal plane detector and uncooled infrared focal plane detector. Cooled infrared detector works at a low temperature vacuum environment with high sensitivity and can distinguish more subtle temperature differences, while uncooled infrared focal plane detector does not need a cryogenic environment and can work at room temperature.
