Description: NLDE1802_TIM-Mikroskopoptik_200px


Thermal imager monitoring of ultra-small components is now possible using a microscope lens from Micro-Epsilon. This special lens is available as an upgrade for the TIM 450 and TIM 640 high resolution thermal imaging cameras, enabling macro shooting of individual components based on a spatial resolution of up to 28µm. The distance between the camera and the object to be measured can be up to 100mm. The camera can be freely positioned within this range. Scalable temperature ranges are from -20°C to 100°C, from 0°C to 250°C and from 150°C to 900°C. Due to the large working distance, temperature measurements of electronic components can be carried out during the measurement of electrical parameters for function tests.

The TIM 450 and TIM 640 camera models can be upgraded with the microscope lens. A process interface cable, a USB cable, a high-quality tripod and the comprehensive TIM Connect evaluation software are included in the scope of supply. The lens enables the display and rapid analysis of quickly changing temperatures and to record radiometric videos and images. The data can be exported and evaluated with other programs.

The new optoNCDT 1750-500 and 1750-750 laser sensors open up numerous other fields of applications optical displacement and distance measurements. Depending on the model, the measuring ranges now extend from 2mm to 750mm. This robust and powerful laser sensor is specially designed for industrial and automation applications, enabling measurements on difficult surfaces such as semi-transparent plastics and ceramics, PCB material, carbon and glass fiber-reinforced plastics. The sensor operates almost independent of the material and color. Its flexibility makes it suitable for real-time quality inspection tasks in almost any industry such as electronics production, automotive, packaging, machine building or automation technology.

The combination of unique performance and a wide range of features result in a sensor that takes a leading role in its class. New evaluation algorithms and enhanced components provide extremely high accuracy and dynamics. Their small light spot size makes them ideal for reliable measurements of the smallest of components. Due to its extremely compact design, the sensor system can also be integrated in a confined installation space.

Measured results can be obtained via analog or the digital RS422 interface. Furthermore, the sensor is equipped with two switching outputs and one input to control different functions. The innovative laser sensor offers a user-friendly web interface that enables the sensor to quickly adapt to the respective measurement task using predefined presets. Highly accurate results are generated without any further complex optimization. Up to eight user-specific sensor settings can be stored.

Capacitive thread sensors for demanding installation scenarios

Capacitive sensors from Micro-Epsilon are now available with a thread. For measurement tasks where the standard sensors cannot be clamped, non-contact displacement, distance and position measurements can be easily carried out using the new threaded sensors.

They are specially designed for machine building applications where the sensors must be mounted at a defined distance e.g. on walls, in bore holes or even very deep drill holes. Capacitive thread sensors can also be mounted on thin walls using two lock nuts on both the inside and outside.

Due to the integrated plug-in connection, capacitive thread sensors from Micro-Epsilon are easy to install. Many sensors are equipped with a permanently integrated cable that is twisted when screwing the cable in. The sensors from Micro-Epsilon are screwed in first and then connected with the cable via the integrated plug-in connection.

capaNCDT sensors stand out due to their long-term stability, reliability and temperature stability. Furthermore, they offer other advantages such as extremely high reliability and stable measurements in the high precision nanometer range. Due to their innovative technology, they can also be applied in harsh industrial environments, as well as being suitable for clean room and ultra-high vacuum applications.

Precise alignment of the cathodes at the electron accelerator

When further developing electron accelerators, high precision capacitive sensors from Micro-Epsilon are used. The Helmholtz Zentrum Berlin uses capacitive sensors with a modular capaNCDT 6220 controller for this measurement task. The capacitive measuring system provides precise measurement results under harsh ambient conditions such as e.g., temperatures in the physical low limit range.

Helmholtz Zentrum Berlin strives to further develop accelerator technologies. The project »bERLinPro« should provide a new technological basis for a linear accelerator with energy recovery (Energy Recovery Linac). Helmholtz Zentrum Berlin relies for this purpose on Micro-Epsilon’s innovative measurement technology based on capacitive flat sensors with a modular capaNCDT 6220 multi-channel controller. This measuring system can be extended to up to four channels and is therefore suitable for flexible measurement tasks.

A photo cathode in a superconductive high-frequency electron gun is used to optimize the source of the electron bunches that are to be accelerated. During further acceleration, the electron bunches thereby generated remain more compact than bunches from other sources. This allows them to be used for achieving higher-quality X-rays, among other things. In the process, the tilting and change of the holder’s position during cooling from room temperature to 2 Kelvin (-271 °C) is monitored.

The requirements for the measuring system are challenging. However, due to its robustness, the capaNCDT 6220 capacitive measuring system is ideal for the harsh ambient conditions prevailing in this measurement task. Very low temperatures in the physical low limit range, ultra-high vacuum, x-ray bremsstrahlung and weak radio-frequency interference create harsh environmental conditions. Furthermore, the sensors from Micro-Epsilon fulfill the requirements with regard to sensor design, temperature resistance and long-term stability. For this measurement task, capacitive sensors with a measuring range of 4mm are used and a linearity of 10µm is required. The sensors achieve resolutions of 0.1µm. Thanks to the system's modular design, all three measuring locations can be captured with just one controller. Data output is via an Ethernet interface.
