Laser Triangulation Displacement Sensors

The non-contact displacement optoNCDT product group uses optical triangulation as a measuring principle. A laser diode projects a visible spot of light onto the target surface (laser class 2). The light reflected from this spot is directed through an optical receiving system onto a position-sensitive element. Optical displacement sensors measure with a large reference distance and a very small measuring spot diameter. Nearly all models work with a high resolution CCD- or CMOS-line and a DSP. Advantages - Small targets through tiny spot size - Long measuring ranges - Large stand off - Extreme resolution - Excellent linearity - High measuring rate - Synchronization of multiple sensors - Measurement of any target
