Accelerator For Cooled Infrared Detector 640x512 Cooled AD Module
EYAS615A Cooled Thermal Module by GST Infrared
Cooled AD Module with 640x512 / 15μm MCT MWIR Cooled Infrared
Detector for Fast Integration
Product Description
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. EYAS615A is a member of EYAS
family with 640x512 / 15μm MWIR cooled detector and RS058
cryocooler integrated.
With EYAS series cooled AD module, it is easy for OEM customers to
carry out fast acceptance test on GST infrared detectors, start
rapid secondary development and shorten their development period of
modules and complete products based on cooled infrared detectors.
Global Sensor Technology specializes in the design, manufacture,
sales and marketing of thermal imaging detectors and infrared
modules. We can provide our customers a variety of infrared thermal
imaging solutions which shorten secondary development time and
greatly reduce the cost for customers.

FAQs
1. What is thermal sensiivity?
Thermal Sensitivity, also named NETD (Noise Equivalent Temperature
Difference), is a key parameter for evaluating medium wave (MWIR)
and long wave (LWIR) thermal imaging cameras. It is directly
related to the clarity measured by the thermal imager. It is a
numerical value representing the signal-to-noise ratio of the
temperature difference and measured in milliKelvins (mK). The
smaller the thermal sensitivity value, the higher the sensitivity
and the clearer the image.
2. 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
