The Optris Xi 1M is a rugged, short-wavelength fixed-mount thermal camera designed for non-contact temperature measurement of hot, low-emissivity materials. By operating within a spectral range of 0.85 to 1.1 µm, the infrared camera for alloys, metals, ceramics, and semiconductors effectively minimizes measurement deviations caused by reflections and emissivity changes, which are common in high-temperature environments.
The Xi 1M of the Xi series measures temperatures from 450 to 1800 °C without sub-range switching. Its CMOS detector provides 396 × 300 pixels with a 15 µm pixel pitch. Furthermore, the thermal camera records full-frame images at 20 Hz and supports line scanning at speeds up to 500 Hz. In this mode, 396 × 8 pixels via Ethernet or 396 × 1 pixels in smart operation enable temperature profiling of moving targets, such as metal strips or rotating parts.
To ensure consistent image sharpness, the Xi 1M features a motorized focus that allows precise focusing at different working distances. Moreover, its IP67-rated stainless steel housing protects the lens and electronics even under demanding industrial conditions. The infrared camera also offers Ethernet, USB 2.0, and RS-485 interfaces. Additionally, it supports Power-over-Ethernet and operates on an 8–30 V DC supply, simplifying integration into existing systems.
For automation tasks, the Xi 1M provides one analog output and one isolated input. When needed, optional process interface modules can add up to three analog or alarm outputs each or industrial fieldbus communication. Furthermore, up to three stackable interfaces can be combined, offering a total of nine independent analog or relay outputs with integrated fail-safe monitoring.
Because of its autonomous operating capability, the thermal camera can perform internal temperature processing and hotspot detection without a computer. The thermal imager directly outputs results as analog, digital, or alarm signals.
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.
