Telecentricity is an extremely useful metric for measuring the amount of perspective error inherent in an imaging system. Determining the degree of telecentricity allows the user to calculate an imaging system’s maximum measurement accuracy. The target can be used to calibrate the degree of telecentricity in both telecentric and non-telecentric lenses. Keystoning becomes visual with the target and can be measured with software. Lenses from our 0.08X MVO® Telecentric Lens (#56-948) to the 5X Mitutoyo Telecentric Objective (#56-986), and any lens in between, including our high resolution Double Gauss lenses, VZM™ Zoom Lenses, and MVO® MMS® interchangeable lens system, can be calibrated or compared with this target.
