Polymer window array for e.g. micro sensor

摘要

Method for manufacturing a polymer body (1) which comprises first areas (2) which are transparent and areas (3) which are non-transparent. A semi-manufactured body comprising said first areas and said second areas which are, however, either both transparent or both non-transparent, is produced by applying a well-known method. When the semi-manufactured body is entirely transparent, the polymer in the second areas is heated to above the polymer's melting temperature and subsequently cooled so slowly as to realize substantial crystallization of the polymer in the second areas. When the semi-manufactured body is entirely non-transparent, the polymer in said first areas is heated to above the polymer's melting temperature and subsequently cooled so quickly as to prevent substantial crystallization of the polymer in the first areas.
