2D Optical Micrometer

Available in three sensor head sized along with the ability to utilize two transmitter-receiver pairs simultaneously to provide high flexibility, the KEYENCE TM-3000 2D optical micrometer is designed to combine the functionality of a laser scan micrometer, machine vision system, and optical comparator into a single device. It includes a high-speed computing CPU and two dedicated image processing DSPs. Using a total of four processors for parallel processing, the series allows up to 1800 images/minute performance. A dual telecentric lens results in a uniform collimated light with a green LED. A two dimensional CMOS array then detects the light to dark transitions on the 2D array to measure the dimensions. Certificates of traceability along with calibration certificates are available upon request. High speed and high precision are a result of sub-pixel processing only in the areas or points designated for measurement. The series offers a ±0.15µm repeatability. It can measure up to 16 points within the measurement area. A combination of 15 measurement and 8 auxiliary modes can support measurements including, but not limited to, hole diameter, center pitch, intersection point, radius, width, angle, perpendicular distance and area. The position correction function automatically orients the test part prior to measurement, eliminating the need for expensive positioning mechanisms. All programming and monitoring can be performed with or without a PC.
