Xi 1M ETH

The Optris Xi 1M is a short-wavelength infrared camera designed for non-contact thermal imaging of complex industrial materials. Operating within the 0.85 to 1.1 μm spectral range, the device captures precise surface temperature data for materials such as steel, iron, brass, copper, tin, carbon, ceramics, and semiconductors. The Optris Xi 1M meets the requirements of demanding industrial applications by providing broad temperature measurement ranges, high accuracy, and configurable field-of-view options.

Non-reflective materials typically exhibit high and stable emissivity across long-wave infrared spectral ranges, regardless of surface texture. In contrast, metallic and reflective materials display low emissivity at long infrared wavelengths, which leads to inconsistent and unreliable temperature measurements.

The short-wavelength spectral range of the Xi 1M infrared camera aligns with the peak emissivity of most metallic materials, enabling accurate remote temperature measurement. According to Planck’s radiation law, short wavelengths result in greater infrared radiation emission, which reduces the impact of emissivity variations on measurement repeatability. Consequently, short-wavelength infrared cameras are preferred for contactless temperature measurement of reflective materials at elevated temperatures. The Xi 1M also features autonomous thermal hot spot detection, increasing its effectiveness in monitoring and inspection tasks. Manufactured in Germany, the Xi 1M demonstrates superior precision, accuracy, and repeatability compared to long-wavelength infrared cameras in industrial applications.

The Xi 1M thermal camera provides mid-resolution thermal imaging at 396 by 300 pixels, supporting temperature measurements from 450°C to 1800°C without the need for sub-ranges. Its high distance-to-spot-size ratio enables accurate temperature data collection from significant distances, exceeding the optical performance of contemporary pyrometers. The motorized focus function allows for precise remote adjustment of the focal point on measurement targets.

The industrial-grade construction of the Optris Xi 1M ensures reliable operation in challenging industrial settings. Its compact, durable, and waterproof design supports both fixed and mounted installations, providing consistent performance in various manufacturing environments.

The Optris Xi 1M uses Ethernet as its primary interface, supporting a 20 Hz frame rate for full-size images. A USB interface is available for sub-images of 132 by 100 pixels at the same frame rate. Autonomous operation reduces the need for extensive software development, facilitating integration into control systems. Additional features include automatic spot detection, direct analog output (0/4-20mA), and compatibility with industrial fieldbus protocols such as Ethernet/IP, Modbus TCP/IP, RS485, and Profinet. The autonomous mode at 20 Hz for sub-images further streamlines integration into industrial machinery.

Where is the Xi 1M thermal camera made, and does it contain memory components sourced from outside the U.S. or the European Union?

The Xi 1M is designed, manufactured, and calibrated in Berlin, Germany. Some electronic components may be sourced from outside the EU or the US. Still, it is important to note that the Xi 1M does not store any thermal images or temperature values in non-volatile memory. The Xi 1M thermal camera only stores full thermal images, thermal video (.ravi files), and temperature values in the customer PC hosting the PIX Connect software necessary to operate the camera. The thermal camera uses memory components inside the thermal camera electronics, which may be sourced outside the EU or the US to store a reference picture (also called dark picture) of the non-uniformity correction paddle or flag and some reference temperatures used to correct temperature drift. All these memory elements are deleted when the power to the camera head is terminated.

Can the Xi 1M thermal camera operate without a connection to a computer?

The Xi 1M thermal camera can calculate the temperature autonomously without a computer. The temperature data can either be transmitted via the USB or Ethernet interface or output via the process interface. Fieldbus communication is also available.

Can the Xi 1M thermal camera send temperature information from spots or areas to my PLC?

The Xi 1M thermal camera can send temperature information or temperature alarms from the Process Interface connection on the back of the camera. A cable with integrated electronics and a terminal block is included with the camera. It can be programmed in PIX Connect software as an Analog Input (AI) and Digital Input (DI) to control the thermal camera or as an Analog Output (AO) to control the process. The signal level is always 0-10 V (DI = 24 V). An optional industrial process interface is also available, delivering up to three independent temperature values or alarms to a user-supplied PLC. USB-RS485 adapters are available for applications with output requirements for more than three areas.

Can we send the raw ADU data from the camera to another commercial software for processing?

As a rule, we do not disclose any information about raw data. The only option is to use the Connect SDK to output the camera’s ADU values as a matrix. However, these ADU values are uninterpreted. The cameras can send the temperature information and the color information to another commercial software for processing.

Does changing the mode from Temperature to ADU in the Connect SDK change the way that the image is displayed?

No, the way the image is displayed does not Change. You can see this in the software examples provided with the PIXConnect software (See the menu HELP => Connect SDK => Examples). Under the configuration menu => External communication => ConnectSDK. You can change the mode from “Temperatures” to “ADU”. This has no influence on the displayed image.

Our company designs and supplies camera systems for steelmaking processes and is exploring different camera types. For this application, would you recommend long-range, near-infrared, or short-wave infrared models?

For steelmaking processes we recommend short-wave infrared cameras as the PI 1M camera, PI 08M camera, PI05M camera , Xi1M camera or Xi 05M camera. Use the lowest wavelength / spectral range as possible!

After connecting the Optris Xi410 to PIX Connect via Ethernet, I get a “frame timeout” error and the infrared image doesn’t appear at all. The camera has the correct IP address and responds to ping. What could be causing this?
