Abstract
An improved window screen in which each strand of the screen is substantially totally transparent is disclosed. In all cases the screen comprises a plurality of optically transparent strands with selected strands intersecting at an angle to form the screen. The strands may be woven or the strands may be bonded at their intersections to form the screen. Light passes through the strands in a distortion free manner. The strands of the screen may either be conventional optical fibers or merely of transparent plastic.
Claims6
An improved window screen comprising a frame supporting an essentially transparent screen including a plurality of woven strands with said strands being the only elements disposed in said frame, and with each of said strands being substantially free of optical attenuation and optical distortion;
- said frame comprising suitable support means for maintaining said woven strands comprising said screen in tension;
- said transparent screen comprising a woven arrangement of elongated substantially round strands each being transparent in all planes such that all light impinging thereon passes therethrough without significant distortion of attenuation.
An improved window screen comprising a frame supporting an arrangement of transparent intersecting strands bonded at their intersections, with said strands being the only elements disposed in said frame, and with each of said strands being substantially free of optical attenuation and optical distortion;
- said frame comprising suitable support means for maintaining said intersecting strands comprising said screen in tension;
- each of said intersecting strands being transparent in all planes such that light impinging thereon passes therethrough without significant distortion or attenuation.
