Tensioned optical element having crimping frame and spring
First Claim
Patent Images
1. An optical element comprising an optical film wherein at least a portion of the optical film is maintained dimensionally stable by a mechanism for application of a controlled tensile force to the optical film, wherein the tensile force is applied by a crimping frame, the crimping frame comprising:
- a first frame component having a semi-circular groove;
a second frame component having an extension;
wherein the first and second frame components interlock together to crimp the optical film; and
a means to fasten the first and second frame components together.

Abstract
The invention provides an optical element comprising at least one optical film wherein at least a portion of the optical film is maintained dimensionally stable by the presence of a mechanism for application of a controlled tensile force to the film. The mechanism for application of a controlled tensile force uses a crimping frame in association with a cantilevered spring which effectively maintains flatness of the film or films.
