摘要 |
<p>A wavelength plate, which comprises a cyclic olefin based resin-containing material and is obtained by combining plural sheets of a retardation film that provides a specific retardation. The resulting wavelength plate (retardation plate) has the same polarizing characteristics against monochromic lights having a different wavelength and can be used as a wavelength plate for optical information recording and reproducing devices.</p> |
