Multi-Function High Magnification Calibration Targets
• Designed for Measurement Calibration; Ideal for Microscopes and Machine Vision Systems
• Includes Ronchi Rulings, Concentric Circles, Square Grids, and a Linear Microscale
• Two Targets Available for Different Magnifications
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 N.I.S.T. 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.

Multi-Function Calibration Target for Low Magnification Systems
• Calibrates Systems from 0,08X to 4X
• Measures MTF, DOF, Resolution, FOV, & Distortion
• N.I.S.T. Certificate of Accuracy Included
Designed to calculate systems from 0,08X to 4X magnification, this Multifunction Calibration Target has the ability
to test many parameters of a visual system at one time, allowing more useful information to be obtained with one
target. Depth of Field can be measured for a number of resolutions, allowing measurements to be made that are
useful for each particular application. System MTF can be measured with frequencies from 5 lp/mm to 80 lp/mm.
The target consists of two framed glass plates with a chrome deposit. The second plate has a circular and grid pattern
to measure planar and tilted plane distortion. The Pattern is designed to make use of the entire FOV without
having to move the target between measurements of each parameter, and it is designed for very high accuracy.
Detailed specifications and a certificate of compliance are included. The target also comes with an operation card,
tutorial CD, and carrying case. Set #58-770 includes both opal and standard chrome on glass targets.
