Blue Laser triangulation sensors for difficult surface types

optoNCDT 1750BL

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.

New: High Precision Blue Laser Displacement Sensor

The optoNCDT2300-2DR is the new model in the high performance optoNCDT 2300 range. The beam path is designed for direct reflection and will find applications in the measurement of high-gloss, shiny and reflecting surfaces. Blue Laser technology from Micro-Epsilon and its optical arrangement result in a laser sensor that is extremely sensitive to changes in distance, which enables very high measurement accuracies. The new model is used in consumer electronics production (e.g. smartphones, tablets and displays), industrial applications and for the production and processing of semiconductors.

Patented Blue Laser Technology

Measurement tasks involving blue laser sensors on red-hot glowing objects exceeding 700 °C and transparent objects such as plastics, adhesives and glass are patented by Micro-Epsilon. The optoNCDT Blue Laser models achieve excellent signal stability and thus precise measurement results on these surfaces.

The new Blue Laser Technology enables the sensor to measure absolutely precisely and reliably on glowing metals and glowing silicon. The blue-violet laser offers decisive advantages here. Even when measuring organic materials such as veneers, wood or skin, the blue laser also contributes to high precision. While allowing higher stability, the blue laser light does not penetrate the measuring object due to the shorter wavelength of the blue-violet laser.

optoNCDT 1710BL blue laser sensors are designed for fast displacement, distance and position measurements on glowing metals. The sensors offer new high-performance lenses, laser control and evaluation algorithms.

optoNCDT 1750BL Blue Laser sensors are designed for high speed displacement, distance and position measurements. They are equipped with new high performance lenses, laser control and evaluation algorithms to ensure precise measurements on different surfaces and materials. The Blue Laser Technology patented by Micro-Epsilon offers decisive advantages compared to red-diode laser sensors. Since the blue laser point does not penetrate the surface, the target is sharply imaged onto the sensor element. This makes it possible to achieve high resolution and reliable signal stability.

While allowing higher stability, the blue laser light does not penetrate the measuring object due to the shorter wavelength of the blue-violet laser.

The high-end optoNCDT 2300BL series operates at a measuring rate up to 49kHz and is therefore ideally suited to precise measurements of fast moving objects. As the controller is completely integrated into the sensor housing, the sensor is ideal for installation in restricted spaces.

Operation is via a web interface that is addressed via an Ethernet interface. This web interface enables making settings for the processing of measured values and signals, e.g., peak selection, filter and masking features for the video signal.

The optoNCDT 2300-2DR high precision laser triangulation sensor is designed for measurements on reflective and shiny targets. Due to its blue laser light, the measurement signal is extremely stable, i.e. the sensor measures down to the nanometer range. An extremely small laser spot size enables reliable detection of very small objects.

The sensor is, for example, used for thickness measurement of flat glass, assembly monitoring of extremely small parts and for distance measurements on annealed glass.

Operation is via a web browser that is addressed via an Ethernet interface. This interface enables making settings for the processing of measured values and signals, e.g., peak selection, filtering and masking features for video signals.
