The retardance of the cellophane was measured to be 170\u00b0. <\/p><\/blockquote>\n<blockquote><p>It may be added that the price per square cm2 of the cellophane half-wave plate is about 1\/3500 of that of a commercially available half-wave plate.<\/p><\/blockquote>\n<p>Iizuka K (2003) Cellophane as a half-wave plate and its use for converting a laptop computer screen into a three-dimensional display.
