Summary and References
In order to model a scanning mirror:
- Use Tools > Add Fold Mirror to place the mirror in its nominal position
- Use Tools > Miscelleneous > Tilt/Decenter Elements to tilt the mirror
- Make the tilt a multi-configuration parameter
- Define as many configurations as are needed to sample the continuous motion of the mirror
- Alternatively, model the continuous motion using Tools > Slider
- If the pivot point of the tilt is about an offset point, use the thickness of the coordinate break surfaces to shift to this point

good article. found it not clear though which surface to choose for the Configuration. should be pointed out that one have to choose the surface BEFORE the mirror (coordinate break)
[Editor's Note: Yes I agree. The value to be put in the MCE is the value you want to switch between configs, so its the scan angle in this case.]

There should be more insightful tid-bits like this. e.g. Adding the z-shift to rotate a surface about some other point is an example of those gems that really helps novices get up and going. Thanks Mark!

Your example presentation and explaining regarding scanning mirror is excellent. Please show the entering of the data such that viewer can learn the Zemax.
{Editor's Note: please email support@zemax.com if you have any specific questions on how to enter data in this example.}
