Because spectral confocal displacement sensor often adopts optical fiber transmission, the raw material cost is slightly higher than that of laser displacement sensor. However, the performance of the spectral confocal displacement sensor is much higher, and the advantages are much more, if the measurement is used in a variety of materials, multiple laser displacement sensors can be replaced, so that the use cost is a big cut. If you also consider the scanning of multiple directions and the shadow effect of laser triangulation, a spectral confocal displacement sensor can replace up to eight laser displacement sensor sensors, and the use cost is extremely advantageous.
