Guide to laser-based displacement
measurement
A comprehensive 25-page guide to non-contact laser displacement and position measurement is now available from sensor manufacturer Micro-Epsilon (UK)
The guide offers technical data and application examples for the company's complete family of optoNCDT laser displacement sensors, now the widest range of optical displacement and position measurement sensors from a single supplier in the world today The Micro-Epsilon optoNCDT Series of laser-based displacement sensors offers customers solutions for every industrial application, from parts measurement, car body positioning in assembly lines and surface contour measurement, through to flatness measurement of integrated-circuit (IC) pins, roundness measurement of catalytic converters and thickness of various sheet or web materials

Lasers offer high accuracies at large distances
Micro-Epsilon has developed a new range of high performance laser sensors, which offer large stand off or base distances, whilst still maintaining high levels of accuracy and resolution
The sensors offer high speed and high resolution, provide a wide measurement range (large stand-off) and offer non-contact, wear-free sensing.
Using the laser triangulation principle, the sensors operate with a laser diode, which projects a visible light spot onto the surface of the measurement target.
The light reflected from the spot is imaged by an optical receiving system onto a position-sensitive element.

Largest choice of current sensors in world today
A new reference guide is now available from sensor manufacturer Micro-Epsilon on the company's non-contact, wear-free eddy current displacement sensors
If the light spot changes its position, this change is imaged on the receiving element and evaluated.
Laser-based optical displacement sensors measure from a large distance to the target using a small spot size, which enables measurements on very small parts.
The large measurement distance in turn enables measurements to be taken against difficult target surfaces such as hot metals.
Furthermore, the non-contact principle enables wear-free sensing because the sensors do not come into any physical contact with the target.
The laser triangulation principle is also ideal for very fast measurements with high accuracy and high resolution.
For demanding applications, the Micro-Epsilon optoNCDT 2200 range is unbeatable.
The linearity and resolution achieved with this sensor represent the limits of laser triangulation sensor technology today.
High measuring rates, extreme accuracy and constant signal stability are carried out at full speed without any signal averaging.
At the other end of the scale is the optoNCDT 1300, a very compact, low cost solution with integral electronics that is ideal for standard industrial and high volume OEM applications.
Due to the compact design of the sensor, integration into tight spaces is possible, for example, on machines or in automation applications.
Even though low cost, this sensor still offers higher resolution than many competing sensor products on the market.
Chris Jones, Managing Director at Micro-Epsilon UK comments: "We are supplying UK customers in a diverse range of industries with our digital and analogue optoNCDT sensors.
If required, we can customise a solution for an OEM application and we can provide a complete range of accessories, including digital processing and readout units, protective housings for harsh environments, set up and configuration software and PCI interface cards that enable the customer to synchronise the acquisition of multiple sensor signals and an encoder.
We've now gained an enviable reputation for specialising in high accuracy thickness measurement applications and in high speed in-process laser-based displacement measurement and inspection".
Another specialist application area for the optoNCDT sensor is in direct reflecting targets such as mirrored objects, glass or highly polished metals.
The Micro-Epsilon optoNCDT 1700(001) sensor is ideal for these types of applications, compensating for the high intensity of the reflected light by using patented, high-speed software algorithm that dramatically reduces signal noise.
Due to the high processing speed of the algorithm, the sensor also measures with the same accuracy on dynamically changing surfaces.
Furthermore, the unit size is identical to the standard optoNCDT 1700 Series and so is ideal for integrating in restricted spaces. Request a free brochure from Micro-Epsilon UK ...
