[l] The measurement range does not include Z-axis
[2] L is the measured length in mm, determined by TZTEK’s inspection method.
[3] Magnification is approximate and depends on the size and resolution of the monitor.
[4] Coaxial lighting is available for option. The specification is same as profile lighting
0.5 x or 1.5 x or 2 x additional lens are available for option with the magnification 13-80 x or 37-240 x or 50-320 x.
