Optoncdt

The optoNCDT BL models are equipped with a blue laser diode and are used when standard sensors with a red laser diode are operating at their performance limits. Due to its shorter wavelength, the blue laser does not penetrate the target surface, projecting a small light spot on the surface and therefore providing stable and precise results. As Blue Laser sensors are equipped with a special filter, they are insensitive to highly emitting objects such as glowing metals. Blue Laser sensors are preferably used with measurements on organic and (semi-)transparent objects, as well as for red-hot glowing metals.

Some measurement tasks require large measuring ranges or a large measurement distance from the target object to be measured. For these types of applications, Micro-Epsilon offers long-range laser sensors that combine high accuracy with a large measurement distance.

The optoNCDT LL laser sensors produce an oval-shaped light spot of just a few millimeters in width which reminds of a short "laser line" (LL). This oval light spot compensates for inhomogeneous surface structures and the so-called "speckling" effect which particularly occurs with metallic surfaces. Combined with special software algorithms, interferences caused by surface roughness, defects, indentations or holes are filtered out. This enables stable and precise measurement results.

The optoNCDT 1320 is a new laser triangulation sensor with compact size for displacement, distance and position measurements. Due to its extremely compact size including integrated controller, the sensor can also be integrated into restricted installation space. Its low weight make the optoNCDT 1320 ideally suitable for applications where high accelerations occur, e.g., on the robot arm or in pick-and-place machines. The optoNCDT 1320 offers high accuracy and adjustable measuring rates up to 4kHz. The Active Surface Compensation (ASC) provides stable distance signal control regardless of target color or brightness. Very small objects can be detected reliably due to the small measurement spot size.
