Keyence calls its TM-3000 the world’s first in-line 2D optical micrometer. By combining the functionality of a laser scan micrometer, machine vision system and optical comparator into a single device, the sensor eliminates the need for expensive positioning mechanisms to ensure the best precision.
The 2D optical micrometer has a dual telecentric lens and a two-dimensional CMOS array. The dual lens creates a uniform collimated light with a green LED. Then the CMOS array detects the light to dark transitions on the 2-D array to measure the dimensions. High speed and high precision result from sub-pixel processing only in the areas or points designated for measurement.
