Keyence Corp. of America's TM-3000 2-D optical micrometer introduces technological advancements to 100% automated high-speed, in-line or off-line measurement and inspection applications. It combines the functionality of a laser scan micrometer, a machine vision system and an optical comparator. Available in three sensor head sizes, it enables use of two transmitter-receiver pairs simultaneously. The micrometer employs a dual telecentric lens to create uniform collimated light with a green LED. A 2-D CMOS array then detects the light-to-dark transitions on the array to measure the dimensions. High speed and high precision are a result of subpixel processing only in the areas or points designated for measurement. Because the system works in two dimensions, it can measure up to 16 points within the measurement area.
