Highly stable reference sources from CI Systems for thermal imagers and electro-optical sensor systems
CI Systems' Extended Area Blackbodies are high-precision infrared reference sources for testing, characterizing and calibrating thermal imagers, IR sensors and electro-optical systems. Their uniform emitting surfaces with high emissivity provide defined and repeatable infrared radiation, enabling reliable measurements under controlled conditions.
The product family covers a broad range of testing requirements. The versatile SR-800N systems are available with different emitter sizes and temperature ranges and provide high temperature accuracy, uniformity and stability. For applications requiring elevated temperatures, the SR-800N-HT high-temperature blackbodies offer operating temperatures of up to 600 °C. The particularly compact SR-33N combines the emitter and controller in a portable all-in-one housing, making it suitable for mobile measurements, on-site calibration and NUC applications. For cameras and sensors with very wide fields of view, the SR-800N-SE features a spherical emitting surface specifically designed for wide-FOV applications.
A key feature of CI Systems' extended area blackbodies is their calibration concept based on removable temperature sensors. Sensors can be replaced within minutes, enabling regular traceable calibration with minimal system downtime. Depending on the model, the blackbodies can be used as standalone reference sources or integrated into automated electro-optical test systems.
Key Features
Portable collimator-based test systems for precise testing of thermal imagers and visible-light sensors in the laboratory, production and field
The ILET (Intermediate-Level Electro-Optical Tester) family from CI Systems provides compact and portable test systems for testing and characterizing thermal imagers and sensors operating in the visible spectral range. Depending on the configuration, the systems enable precise electro-optical testing not only in the laboratory, but also on production lines, in the field or in environmental chambers.
The system combines a reflective off-axis collimator with one or more radiation sources and a manual or motorized target wheel. Available sources include high-precision blackbodies for infrared testing as well as integrating spheres and other light sources for VIS and SWIR applications. The collimator provides a defined optical image of a distant target, creating reproducible conditions for evaluating electro-optical sensors.
With different clear apertures from 4 to 6 inches and a broad spectral range from 0.4 to 15 µm, the ILET family can be configured for a wide variety of test requirements. CI Systems' optional CTE software provides computerized control and automation of test procedures, improving measurement repeatability and objectivity while reducing the time required for recurring tests.
Key Features
Compact UV, SWIR and IR simulators for realistic functional testing in the field and laboratory
CI Systems' Mobile Signal Simulators (MSS) are compact, portable test systems designed to verify the readiness and performance of Missile Warning Systems (MWS). They enable reproducible testing directly on aircraft or vehicles as well as under controlled laboratory conditions.
At the core of the systems are miniature radiation sources generating characteristic optical signals in the UV, SWIR or IR spectral range. An integrated microprocessor modulates the radiation to realistically simulate the characteristic signatures of different threat scenarios. Test profiles can be configured via software and uploaded to the device, allowing defined tests to be repeated and the correct response of the warning system to be verified.
The product family includes several versions for different sensor and warning technologies. The MSS-UV is designed for testing UV-based systems, while the MSS-SWIR covers the short-wave infrared range. The MSS-IR simulates infrared signatures and is available in single- or dual-band configurations. In addition, the Collimated MSS generates a collimated infrared beam for targeted testing and calibration of onboard IR warning systems. The portable system can optionally be battery powered and combined with a theodolite for precise alignment.
Thanks to their compact and rugged design, MSS systems are suitable for routine functional and readiness checks as well as testing immediately prior to operation.

New frontend integrates reference channel, signal generator and WiFi for more efficient laser vibrometry
Polytec is expanding its modular VibroFlex laser vibrometry platform with the new Connect+ Frontend. The system integrates a reference channel, signal generator and WiFi in one central hardware unit and increases the bandwidth to up to 32 MHz. Users in research, development and production testing benefit from more compact measurement setups and advanced analysis functions.
Less hardware, more functionality
With the integrated reference channel and signal generator, users can acquire complete transfer functions (FRF) phase-synchronously without additional external measurement hardware. An encoder and tacho input adds functions for order analysis and run-up measurements.
“Many users wanted to integrate measurement setup, synchronization and data acquisition more closely within the system. With Connect+, we have addressed exactly these requirements,” explains Frank Schmälzle, Product Manager Vibrometry at Polytec.
Extended bandwidth and wireless integration
The bandwidth of up to 32 MHz supports high-frequency applications such as ultrasonic and structural analysis. For multi-channel setups, the new PTP-based synchronization enables precise timing between several frontends.
The integrated WiFi function also enables wireless system control and data transfer via VibSoft software. This significantly reduces cabling effort, especially at measurement locations that are difficult to access or safety-critical.
Fully compatible with existing VibroFlex systems
The modular principle of the VibroFlex system remains unchanged. Existing VibroFlex systems can use the new Connect+ Frontend without replacing existing sensor heads.
