Notes and Changes:

As per attached e-mail the changes indicated with this DCN are: -

1)Thin Compensation plate barrel pattern modified at location of prisms. This change of pattern and subsequent mask change only applies to the Thin Compensation plate.

2)Updating the Thin Compensation Plate and Compensation plate assemblies with the correct prism DCC number called out.
