An optical comparator measures the dimensions of an object, comparing it to the required values and informing the operator if the object is within the allowed tolerances. By providing both overwhelming measurement speed and high measurement accuracy, Keyence IM Series image dimension measurement system changes your measurement operations dramatically. KEYENCE’s specifically designed lens provides a super wide field of view. Coupled with the Auto-Focus capability, the IM Series ensures the part is always in focus regardless of height differences. This allows optimal accuracy at all times without worrying about setup.
