A method by which an aluminized Parlene, Mylar or similar
thin plastic film (in the order of 3~7 microns thick) can be

initially used as a mirror surface in an optical system and
easily replaced by virtue of manually or automatically ad-S

vancing a heretofore protected new section of film strip into
position. Location is determined by the base flange position.
Flatness is a function of tension of the film applied by the
cassette drive mechanism, An air space separates the stretched
film from the mirror base in the imaging area.

In operation a new mirror surrace is advanced into position
by manually advancing the take up cassette or pushing a
button which energizes a drive train to automatically ad-
vance a length of film sufficient to cover the mirror base.
