Laser sensors have large stand-off distances
High performance laser sensors, with large stand-off distances, are work in applications where it is not possible to mount the sensor close to the measurement target.
Laser profile sensor software exports to any CAD
3D visualisation software for laser profile sensors enables users to export captured 3D data to other software and the data can be exported as a 3D point cloud to any CAD/CAM software application.
It is believed to be the widest range of optical displacement and position measurement sensors available from a single global supplier.
Micro-Epsilon's optoNCDT Series of laser-based displacement sensors are available for every industrial application including the following.
* Parts measurement.

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.
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, Micro-Epsilon's 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 sensor's compact design, 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 competing sensor products on the market.
Chris Jones, managing director at Micro-Epsilon UK commented: "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.
Micro-Epsilon's 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 algorithm's high processing speed, 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 ...
