Laser line triangulation sensor
06/01/2022
Precision sensor manufacturer Micro-Epsilon continues to develop and expand its already comprehensive range of laser triangulation sensors with the introduction of the optoNCDT 1900 LL laser line sensor, as well as the addition of new larger measuring ranges for the optoNCDT 1900.
Ideally suited for both dynamic and high-resolution measurement tasks, the optoNCDT 1900 LL is designed for distance measurements on shiny, metallic, rough and structured surfaces. A special cylindrical lens expands the conventional point of light into an oval-shaped light spot (small laser line). Optical averaging via the oval light spot compensates for any unevenness of the target surface.
The oval-shaped light spot and intelligent software algorithms filter out disturbances caused by surface roughness, indentations or small holes on the surface. It also helps to compensate for the laser penetrating into the surface. The laser line reveals its major strength in measurement tasks that involve a pure distance change in the z-axis. With movements in the x- or y-axis on the target, the measurement values are more stable than those from comparable point laser sensors, it is claimed.
The optoNCDT 1900 LL is available in measuring ranges of 2 mm, 10 mm and 25 mm. Micro-Epsilon has also expanded its optoNCDT 1900 series of point laser sensors with new additional measuring ranges. The sensor is now available in seven versions with measuring ranges of 2 mm, 10 mm, 25 mm, 50 mm, 100 mm, 200 mm or 500 mm.
With its unique combination of speed, size and performance, the optoNCDT 1900 is suitable for a wide range of measurement tasks in automation, machine building, robotics, automotive production, 3D printing and coordinate measuring machines. The sensor itself has dimensions of 70 × 31 × 45 mm and weighs just 185 g. The measuring rate is continuously adjustable up to 10 kHz and can be individually adapted to suit each measurement task. Highly flexible cables and a robust IP67-protected aluminium die cast housing make the sensor ideal for industrial use. A compact sensor housing with innovative mounting sleeves ensures a repeatable sensor position and alignment with the target.
