The calibration process should address bulb alignment, mirror & lens cleaning, stage flatness, screen parallelism to stage, screen centering, magnification accuracy, and linear accuracy

Some of the key factors to consider:

?

1????????????? Bulb Alignment has a major impact on edge definition

2????????????? Mirror and Lens cleaning contribute to image & edge definition and repeatability

3????????????? Stage nicks and surface defects can cause misorientation of datums

4????????????? Screen Parallelism issues can cause additional linear axis error

5????????????? Screen Centering error causes intersection point errors

6????????????? Magnification Error causes overlay chart utilization error

7????????????? Linear Scale alignments / Micrometer Head /Rotary Encoders issues cause linear error

?

Unfortunately, all too many calibrations only concentrate on observing the resulting linear accuracy, which has a high probability of significant uncertainties beyond the “certified accuracy”
