About us

Micro-Epsilon is a medium-sized family-run company, which plays a leading role in measurement technology. For more than 45 years we have continuously offered reliable, high performance, unique solutions particularly when high precision measurement or inspection is required. Our product range covers sensors for the measurement of distance and displacement, sensors for IR temperature measurement and color detection, as well as systems for dimensional measurement and defect detection.

Innovative products that provide the very highest levels of precision are created through intensive, research and development processes, unique know-how and a broad network of collaborative operations, which are essential for such high performance measurement systems.We understand that our customers are our business partners, which creates a win-win situation for both parties. Our products often provide customers with a genuine competitive advantage. However, this is only the case if the products are higher precision and so provide a clear, decisive competitive edge. With more precision.

Products and services

The measurement principle of laser triangulation is simple:the sensor operates with a laser diode, which projects a visible light spot onto the measurement target.

The reflected light is imaged by anoptical receiving system onto aposition-sensitive element. If thelight spot changes its position, this
change is imaged on the receiving element and evaluated. Nearly allmodels of the product group optoNCDT by Micro-Epsilon work with a high-resolution CCD- or CMOS-line. The product group optoNCDT includes nine series of laser sensors.

Sensors vary from basic models for easy tasks, to standard models for very economical laser measurements,up to high-end products for fast,high-resolution measurements. The 49 different sensor models, with measuring ranges from 0.5mm up to 1,000mm, cater for a wide range of applications. In addition, all sensors can be customized to find the appropriate sensor for each measurement task.
confocalDT IFC2421/22

The confocalDT 2421/2422 controllers are used for distance and thickness measurements of diffuse reflecting and specular surfaces. Available as either a single- or a dual-channel version, these confocal chromatic measurement systems enable a low cost solution especially for high volume applications. The active exposure regulation feature in the CCD array enables accurate, fast surface compensation on changing surfaces.

Application of line laser sensor and laser displacement sensor in railway welding -2D/3D
Many years ago, when we were in the middle of a train, we couldn’t get rid of the noise of “dangling and jingle”. The reason is that it is subject to the technical level at that time. In order to prevent the deformation of the rail caused by thermal expansion and contraction, only gaps can be left between the rails, which greatly reduces the running comfort and safety of the train.
Today's high-speed trains can reach speeds of more than 300 kilometers per hour. Railroad tracks can no longer leave any gaps, even slight deviations in straightness, which can lead to major safety hazards. The rails cannot be extended indefinitely when they leave the factory. How to quickly connect two sections of rails, automatic welding, and how to detect the quality of weld grinding after welding have become a problem for railway engineers.
The seamless welding technology can make the welding points almost invisible between the two sections of the rail, and the transition is natural. On the high-speed rail, the "jingle" sound will become history. After the high-speed rail is laid, the technicians will use advanced welding technology to weld and polish the rails. A strip of 500 meters long and weighing 30 tons is welded into an extra long seamless line to achieve a track paving. There is a soft connection at the expansion joint, and there is reserved space for expansion after being heated. I can't see an interface, it's like two complete rails going through. Such high-precision technology can guarantee the stability of driving.
The traditional rail welding uses the aluminothermic method, which is actually a method of welding the rails with an aluminum thermal reaction. In other words, steel is welded on site, and then molten steel is injected into the gap between the two rails to achieve the welding effect.
Expression of aluminothermic reaction: 2Al+Fe2O3=2Fe+Al2O3 (reaction conditions are high temperature)
