Test Targets allow the calibration of measurement functions in microscopes through objects in different forms and sizes or of resolution of an optical system measured in Line Pairs per mm.
The Target allows the calibration of measurement functions in microscopes. A field of objects in different forms and sizes allow the user to check: rectangles, ellipsis, circles, rings and even fibre-shaped objects. To determine optical distortions there are three different sized arrays of cross-targets. The smallest Object is as small as 5μm.
This Resolution test target is NBS tested. It consists of 49 Line tests, each with 5 perpendicular and horizontal lines. The distances varies between 1 and 250 line pairs per mm. The length of the Line is 12 times the thickness.
