1. ZTF Filter Options P. Jelinsky 2013-02-12 2013-02-01ZTF Technical Meeting 1

2. Optic Terminology 2013-02-01ZTF Technical Meeting 2 Filter/ Focal Plane Corrector Window 12 flatteners 12 detectors

3. Filter Options Case A –Filter at the front of corrector. (Only Window and Flattener) Case B –Flat filter between mirror and window. Case C –Fixed filters (make the flatteners the filters, window only). Case D –Fixed filters (make the flatteners the filters, but keep the current "filter" as a corrector). 2013-02-01ZTF Technical Meeting 3
