ABSTRACT:
A composite frame for a free-standing membrane is provided. The frame includes a first frame member which is to be mounted to a planar surface such that a working area is defined on the planar surface, a second frame member for peripherally supporting the membrane, and a removable mounting between the first and second frame members so that the membrane protects and covers the working area. Another aspect of the disclosure is a method for using a pellicle, which includes the steps of mounting a first frame member to a planar surface such that a working area is defined, and then removably mounting a pellicle to the first frame member so that the working area is protected by the pellicle.
