1. A polarizing beam splitter, comprising:
- a polymeric multilayer reflective polarizing film comprising alternating layers of two polymeric materials, at least one of which is birefringent and orientated;
a pressure sensitive adhesive disposed on the polymeric multilayer reflective polarizing film wherein the pressure sensitive adhesive has aggressive and permanent tack, adheres with no more than finger pressure, has sufficient ability to hold onto an adherand, has sufficient cohesive strength and requires no activation by an energy source; and
a first rigid cover disposed on the pressure sensitive adhesive.
