Imperx - Industrial Cameras

C-4440-cmos-cameraThe C4540 is our most technically advanced, ruggedized, progressive scan digital camera in a compact design ideal for industrial, scientific, medical, aerospace, transportation and other applications. The C4540 incorporates a number of unique features tailored to reduce system complexity, maximize interface bandwidth, and expand the usable operational range.

The C4540 features the Sony Pregius STM IMX531 Global Shutter CMOS image sensor with a native resolution of 4512 x 4512 in a 1.1” optical format delivering up to 55.8 frames per second with a dual CXP-6 CoaXPress output. The Pregius S technology uses a stacked back-illuminated pixel structure offering reduced pixel size, increased peak quantum efficiency, and improved sensitivity with fast lenses. A dual ADC mode enables HDR imaging by combining high gain and low gain lines from the same frame within the image sensor. Short interframe time of 100 ns combined with the camera’s high frame rate makes the camera especially suitable for PIV applications. The camera offers low latency, fast frame rates, exceptional dynamic range and supports strobe outputs, trigger inputs, automatic exposure, automatic gain control with multiple LUTs, and other high-value functions.

The CXP-C4540 camera’s low dark current, excellent uniformity and low power dissipation (<5W), means the camera can be conductively cooled making it ideal for high reliability and precision imaging applications. It operates over an extended temperature range from -30 °C to +75 °C making this camera suitable for use in even the harshest of environments.

The Imperx Cheetah line provides excellent image quality with Imperx proprietary processing. In addition, Imperx puts you in control and gives you full access to raw data without corrections. Using the simple, intuitive GenICamTM compliant user interface, you can quickly apply image corrections, if desired. The C4540’s flexibility, image quality, and speed make it suitable for a broad range of diverse and demanding applications, but “one size doesn’t fit all,” and Imperx can help optimize the camera to your exact requirements.
