2.3 Key features of the X8400sc camera
•1.3 million pixels – 1280x1024
The X8400sc provides 1.3 million pixels per image, allowing enlarging the area under
inspection with same instantaneous field of view (IFOV) lenses or increasing the spatial
resolution with the same field of view (FOV). The snapshot integration ensures that all pixels
are temporally coherent.
•Fast Frame Rate
The FLIR X8400sc Series have an adjustable frame rate of up to 106 Hz full frame and more
than 3 kHz at 48x4. Windowing allows a subset of the total image to be selectively read out
with user adjustable window size. The sub-sample windows can be arbitrarily chosen and are
easily defined.
•14-Bit Digital Image Data
The X8400sc camera detector is digital. The A/D conversion is performed directly into the
ROIC in 14-bit depth. The embedded digitalization improves noise and linearity performances
to an outstanding standard.
•Outstanding measurement accuracy
High accuracy of +/- 1ºC or +/- 1% produces sensitive thermal images. The FLIR X8400sc
can measure temperatures up to +3,000º C. The FLIR X8400sc detects temperature
differences smaller than 25mK (18mK typically).
•CNUC™ Calibration
CNUC™ is a proprietary calibration process that provides beautiful imagery and
measurement stability. CNUC™ allows for flexible integration time adjustments without the
need to perform non-uniformity corrections. CNUC™ calibration also produces accurate
measurement stability regardless of camera exposure to ambient temperature variations.
•Hypercal™
Hypercal™ ensures the best measurement range with the highest sensitivity. Simply set the
desired lower and upper temperature limits and the camera will automatically adjust to the
appropriate integration (exposure) time.
•Auto exposure
The camera automatically adjusts its temperature range to best fit the thermal scene.
•Presets
Up to eight presets and their associated parameters, such as integration time, frame rate,
window size and window location, are available for instant selection with a single command.
These presets can be used in Dynamic Range Extension (DRX) mode (also called
Superframing”) which allows the acquisition of thermal data from up to four user-defined
temperature ranges simultaneously, then merges those streams into a single real-time data
stream that spans all four temperature ranges, effectively extending dynamic range from 14
bit to 16 bit.
•Multiple Triggering Modes and Synchronizing Interfaces
The X8400sc camera provides different interfaces to support maximum flexibility for
synchronizing the camera to external events, as well as synchronizing external events to the
camera.
oSync In (TTL)
oSync Out
oTrigger In
•Multiple Video Outputs
The X8400sc camera features multiple independent and simultaneous videos:
oDigital 14-bit video – CameraLink® Base or Medium
oDigital 14-bit video – Gigabit Ethernet – GigEVision Compliant
oDigital 8-bit Video – DVI format 1080p30 digital output
•Wide range of interchangeable lenses
The FLIR X8400sc comes with an advanced high performance optical design with lens
recognition and automatic measurement adjustments. It is also possible to manually adjust
the focus directly on the camera. A temperature probe is integrated in the lens for improved
measurement accuracy and drift compensation.
A wide range of lenses and various extension rings are available.
•Motorized filter wheel
The FLIR X8400sc contains a 4 slot motorized filter wheel with automatic filter recognition
and measurement parameter adjustment. The removable filter holders contain an integrated
temperature probe for improved measurement accuracy.

The LCD touchscreen can be removed from the camera when the FLIR X8400sc needs to be
installed in a hard to reach position. Just position the camera and control it from a distance.
•Wi-Fi
The camera embeds a Wi-Fi interface which enables to control it via a smart phone (iPhone)
or a tablet PC (iPad).
•Video Color Palettes
The X8400sc camera supports a selection of standard and user-defined color palettes (or
grayscale) for the DVI video.
•Configuration management
Save your camera configuration to the SD-Card when loaning your camera to your colleague.
Once back, just insert your SD-card and get the camera up and running with exactly your
configuration. Stop wasting time to reconfigure your thermal measurement system.
•Global Status LED

4.4.6 Frame frequency
General Frame rate is the number of images taken by the camera per second. Achievable frame rates
are based on camera settings, camera overhead, and integration settings.
4.4.7 Synchronizing the camera to an external signal
Note
•Refer to §6.7 Camera Synchronization for detailed information on synchronization
General The camera can be synchronized to an external signal. This is useful for instance when
considering a brake disk testing. A signal from the testing machine will synchronize the
camera to the disk speed.
Synchronization parameters are set through the ResearchIR Max user interface:
1 Activate / Deactivate external synchronization. Select the active edge and input
impedance.
2 Based upon camera configuration such as window size, integration time or integration
mode, the maximum allowable Sync IN frequency is displayed.
3 The actual Sync IN signal frequency is measured by the camera and displayed here. If the Sync IN frequency is higher than the maximum allowable frame rate, a warning
message is displayed. In that case the input signal is under sampled.
4 The jitter on the Sync IN signal, which is typically one pixel clock, is displayed here.
5
Integration time length is displayed here. The integration time is defined on the
measurement range control.
6 A delay between the Sync IN signal and the start of integration time can be defined
here.
7 Several camera signals can be routed to the Sync OUT connector. The polarity of these
signals is also defined here.
