Teledyne Calibir GXM

Teledyne’s Latest Microbolometer Technology

The Calibir GXM camera family features our latest microbolometer sensor, designed, fabricated, and packaged in our own foundry. With great sensitivity in longwave infrared range (8-12 µm), it features both shutter and shutterless operation and rapid image output on power up while delivering uniform response over the entire operating temperature range, making it an ideal component for thermal imaging systems requiring uninterrupted image acquisition. The GXM series also offers our own advanced 21-bit ADC design for unparalleled intra-scene dynamic range without the need for a gain reduction, allowing for the best possible NETD over a vast range of temperature (>600C).

Export Control

The Calibir GXM cameras are currently classified as a “Dual Use” item under Group 1 (1-6.A.3.b.4.b) of the Canada Export Control List and Category 6 (6.A.3.b.4.b) under the Wassennaar Arrangement on Export Control for Conventional Arms and Dual-Use Goods and Technologies. As such, the Camera is subject to export control – export authorization is required to export the Camera from Canada, whether on a permanent or temporary basis.

Thresholding with LUT

Calibir GXM and its control software allow you to set your own LUTs (look up tables); with this control, you can mark certain temperatures with color while leaving the rest monochrome. For example, show everything between 38 and 41°C as red.

Frame Averaging for Extra Precision

Calibir GXM supports a smart frame averaging feature that can be tuned to minimize read noise according to your tolerance to movement, allowing any detection system to reach extremely low NETD values.

Superior Dynamic Range

The details in this thermal image of an electric heater element shows Calibir GXM’s exceptional range (right) compared a third party detector (left). With a temperature range over 1500°C with consistent NETD <0.05°C, enabled by our advanced 21-bit ADC, Calibir GXM offers unprecedented radiometric detail. For the much smaller temperature range of fever detection (~30°C to 45°C), Calibir GXM can output an 8 bit (sub)range of values for convenient integration that still has 21-bit precision and accuracy.

Regions of Interest (ROI) and Metadata

Up to two Regions Of Interest (ROIs) can be defined inside the camera: size, location, and the Min/Max/Average temperatures in each ROI can be displayed as well as the Min/Max/Average indication on the entire image. All this information is available in an easy metadata protocol that can be used to launch alerts or to combine with other types of image sensor (like visible CMOS sensor for identification for example). Metadata with ROIs temp information can be added to the image buffer.

Application Highlight: Detecting Elevated Skin Temperature with Calibir GXM

Calibir GXM has nonuniformity correction and is factory calibrated with a proprietary flux/temp base algorithm to account for black-body/Planck’s Law (IR flux from an object does not change linearly with object temperature). The result is camera output that is linear with IR flux, and each output color or grey level corresponds to an unique object temperature, simplifying your system.
