+ 2 microns

- 2 microns

0.000

Error in this area is 1 micron or less

Approx. +/- 4 mm of measuring area – each

vertical line on the graph equals 1 mm.

Total Error = +/- 3.3 microns

+ 2 microns

- 2 microns

0.000

Each green vertical line equals 1 mm of

measuring area on the detector. The total area

here is 8 mm.
