Innovative Blue Laser Technology with Patent
Laser profile scanners and laser triangulation sensors equipped with a blue-laser diode offer numerous advantages over red-diode lasers. For decades, sensor specialist Micro-Epsilon has played a leading role in measurement applications based on Blue Laser Technology and has a worldwide applied-for patent on these applications, particularly on red-hot glowing and (semi-) transparent objects.
Instead of a red laser line, the Blue Laser diode generates a blue-violet laser beam with a wavelength of 405nm. The sharper focus enables a sharper projection of the laser beam and therefore increased accuracy. In numerous measurement tasks, the technology already patented in several countries by Micro-Epsilon offers decisive advantages compared to red-diode laser sensors. The sensors are equipped with new high-performance lenses, new intelligent laser control and innovative evaluation algorithms. Unlike the long-wave red laser, the short-wave, blue-violet laser light hardly penetrates the measurement object. Particularly with organic materials such as wood or semi-transparent objects such as adhesive beads or plastic profiles, this effect becomes distinctively visible. The blue laser point or blue laser line is sharply imaged onto the surface and projected onto the sensor element, providing stable and precise measurement results.
Micro-Epsilon Blue Laser Technology also has important advantages on red-hot glowing objects. The long-wave radiation emitted by red-hot glowing objects dazzles the receiving elements of laser sensors that operate using red laser light.

Micro-Epsilon Blue Laser Technology also has important advantages on red-hot glowing objects. The long-wave radiation emitted by red-hot glowing objects dazzles the receiving elements of laser sensors that operate using red laser light. Blue Laser Sensors are equipped with optical elements that cannot be influenced by this radiation, which therefore enables stable distance and profile measurements of slabs, cast parts and glowing brake disks. Measuring the deformation of brake disks under load while braking is an ideal task for the optoNCDT laser sensor. Due to the short wavelength of the blue-violet laser employed, the light emitted from the thermocouple does not dazzle the sensor, as the intrinsic long-wavelength incandescent radiation is a long way off the 405-nm wavelength of the blue-violet laser, and it is effectively blocked by the high quality interference filters used.

Sensor solutions for the reliable inspection of wind turbines
Due to safety and cost reasons, wind turbines require 24/7 monitoring. Lightning, defective rotor blades or tower movements due to localized storms can have serious consequences until the wind turbine finally collapses. Precision sensor technology from Micro-Epsilon is already used during production as well as in the real-time monitoring of active plants. The sensors enable the plant operator to intervene early during production or to switch off the running wind turbine early enough to avoid danger or damage. Targeted monitoring using modern sensor technology reduces the costs of maintenance and servicing.
How to Reach Unrivaled Precision in Distance and Thickness Measurements with Confocal Sensors
Sensors that measure the distance to an object have many application areas in the manufacturing industry and in quality control. The requirements for the measurement system differ substantially depending on the respective application. The distance to be measured, the speed, the accuracy required and the type and surface of the object are just a few of the numerous factors that determine the choice of sensor. Sensors based on an optical measurement principle have the advantage of being neither subject to effects of electromagnetic interference fields, nor to the effects of wear. In addition, optical measurement principles enable very high resolution, accuracy and repeatability using a true non-contact technology.
Learn how capacitive sensors open up new perspectives
Conventional capacitive sensors are known from simple tasks e.g. as proximity sensor or for fill level measurements. With corresponding design and evaluation electronics, these sensors can also be used for high precision displacement and position measurements, achieving resolutions well below one nanometer. Capacitive displacement sensors are typically used in applications where fast displacement changes have to be acquired, where no forces can be exerted on the measurement object, where highly sensitive surfaces do not allow any contact, or where a long service life of the sensor is required. Capacitive displacement sensors from Micro-Epsilon have proven themselves in various industries and measurement tasks.
A Comparison of Blue and Red Laser Triangulation Sensors
Although red laser triangulation displacement sensors have been in use for more than 20 years, blue laser versions are also now available. Before selecting which colour to use, it is important to understand which type performs best on which target material.
Non-contact temperature measurement of plastics
In plastics processing where thermal processes play a particularly important role, temperature is the crucial measurement parameter. Only precise temperature control ensures high, consistent product quality. Micro-Epsilon provides suitable measurement technology from a single source for almost any material or polymer.
Thickness Measurement with Laser Displacement Sensors
Laser displacement sensors are often used for measuring distance, movement and dimensions. If the measured values from two sensors are evaluated together, the thickness of an object can be determined from this. However, in order to achieve a precise statement of the target thickness from the combined signals of two sensors, there are a number of factors that need to be taken into account.
