How to Enhance Blocking Using Two Filters

One plus one does not always equal two when it comes to optical filters and blocking but can be made to do so with careful design and use considerations:
Case 1: Two Filters in Parallel at Normal Incidence
Case 2: Two Filters in Parallel at Non-normal Incidence
