LWIR Uncooled 640x512 12μm Thermal Imaging Module with 25mm Lens for Outdoors
TWIN612 thermal module is a new arrival product developed by Global Sensor Technology. It integrates 640×512/12µm ceramic package uncooled infrared detector. With typical NETD＜40mk, the TWIN612 thermal module could present clearer, sharper and more detailed image.
With temperature measurement range of -20℃~150℃/0~550℃, accuracy of ±2℃ or ±2% and frame rate up to 30Hz, the thermal module guarantees smooth thermal image and accurate temperature measurement.
The TWIN612 thermal module has the advantages of compact design, light weight structure and power consumption as low as 0.8w. With enhanced image algorithms and temperature measurement function, the TWIN612 thermal module presents more stable images and accurate temperature.
Ceramic packaging process is similar to metal packaging, which is a mature infrared detector packaging technology. Compared with metal packaging, the volume and weight of the packaged detector will be greatly reduced. Thus, the TWIN612 thermal module could be applied to industries that have strict requirements on size, weight and power consumption.

1. DRI Range
It is a means of measuring the distance at which an infrared detector can produce an image of specific target and can be divided into detection range, recognition range, identification range.
D (Detection): ability to distinguish an object from the background
R (Recognition): ability to classify the object class (animal, human, vehicle, boat …)
I (Identification): ability to describe the object in details (a man with a hat, a deer, a Jeep …)
According to Johnson's criteria, when the probability of target detail visible at the DRI distance is 50%, the minimum number line pairs of the target is 1:3:6 (or 1:4:8), and the corresponding minimum number of pixels is 2:6:12 (or 2:8:16).
Assuming that the target diameter is H, the focal length is f, the pixel size is d, and the number of line pairs is n, then the view distance L=H×f/(2n×d)
