Multi-Function Calibration Target for Low Magnification Systems
Multi-Function Calibration Target for Low Magnification Systems
產品名稱 : Multi-Function Calibration Target for Low Magnification Systems
產品說明 :
Designed to calibrate 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, 100 x 166 x 1.5mm, glass plates with 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.
