Multi-Function High Magnification Calibration Targets

Use these "all-in-one" targets to measure microscope and vision system parameters, without separate calibration targets. Targets will test and calibrate our Mitutoyo objectives, Zeiss microscopes, and high magnification video lenses for resolution, distortion, and depth of field (DOF). Targets include variable frequency Ronchi rulings, sets of grids and concentric circles with varying line spacings and widths, a microscale, and edge blocks to prop up target for DOF measurements. A user information card, complete manual on CD, and NIST certificate are provided.

Use Low Frequency Target for optical systems with 4X to 20X objectives. Target is useful for machine vision systems with low magnifications and long focal distances.

Use High Frequency Target for optical systems with 20X to 100X objectives. Target is useful for microscopes and other systems with high magnifications and short focal distances.
